Spline deviation from the circle in radius would be given by:
error = sqrt (x**2 + y**2) - 1
A simpler error function to work with is:
e = x**2 + y**2 - 1
From "Good approximation of circles by curvature-continuous Bezier
curves", Tor Dokken and Morten Daehlen, Computer Aided Geometric
Design 8 (1990) 22-41, we learn:
abs (max(e)) = 4/27 * sin**6(angle/4) / cos**2(angle/4)
and
abs (error) =~ 1/2 * e
Of course, this error value applies only for the particular spline
approximation that is used in _cairo_gstate_arc_segment.

| cairo-cache-private.h |
_cairo_cache_entry:
A #cairo_cache_entry_t contains both a key and a value for
#cairo_cache_t. User-derived types for #cairo_cache_entry_t must
have a #cairo_cache_entry_t as their first field. For example:
typedef _my_entry {
cairo_cache_entry_t base;
... Remainder of key and value fields here ..
} my_entry_t;
which then allows a pointer to my_entry_t to be passed to any of
the #cairo_cache_t functions as follows without requiring a cast:
_cairo_cache_insert (cache, &my_entry->base, size);
IMPORTANT: The caller is responsible for initializing
my_entry->base.hash with a hash code derived from the key. The
essential property of the hash code is that keys_equal must never
return %TRUE for two keys that have different hashes. The best hash
code will reduce the frequency of two keys with the same code for
which keys_equal returns %FALSE.
The user must also initialize my_entry->base.size to indicate
the size of the current entry. What units to use for size is
entirely up to the caller, (though the same units must be used for
the max_size parameter passed to _cairo_cache_create()). If all
entries are close to the same size, the simplest thing to do is to
just use units of "entries", (eg. set size==1 in all entries and
set max_size to the number of entries which you want to be saved
in the cache).
Which parts of the entry make up the "key" and which part make up
the value are entirely up to the caller, (as determined by the
computation going into base.hash as well as the keys_equal
function). A few of the #cairo_cache_t functions accept an entry which
will be used exclusively as a "key", (indicated by a parameter name
of key). In these cases, the value-related fields of the entry need
not be initialized if so desired.

_cairo_cache_init:
@cache: the #cairo_cache_t to initialise
@keys_equal: a function to return %TRUE if two keys are equal
@entry_destroy: destroy notifier for cache entries
@max_size: the maximum size for this cache
Creates a new cache using the keys_equal() function to determine
the equality of entries.
Data is provided to the cache in the form of user-derived version
of #cairo_cache_entry_t. A cache entry must be able to hold hash
code, a size, and the key/value pair being stored in the
cache. Sometimes only the key will be necessary, (as in
_cairo_cache_lookup()), and in these cases the value portion of the
entry need not be initialized.
The units for max_size can be chosen by the caller, but should be
consistent with the units of the size field of cache entries. When
adding an entry with _cairo_cache_insert() if the total size of
entries in the cache would exceed max_size then entries will be
removed at random until the new entry would fit or the cache is
empty. Then the new entry is inserted.
There are cases in which the automatic removal of entries is
undesired. If the cache entries have reference counts, then it is a
simple matter to use the reference counts to ensure that entries
continue to live even after being ejected from the cache. However,
in some cases the memory overhead of adding a reference count to
the entry would be objectionable. In such cases, the
_cairo_cache_freeze() and _cairo_cache_thaw() calls can be
used to establish a window during which no automatic removal of
entries will occur.
Returns: the newly created #cairo_cache_t

cairo_debug_reset_static_data:
Resets all static data within cairo to its original state,
(ie. identical to the state at the time of program invocation). For
example, all caches within cairo will be flushed empty.
This function is intended to be useful when using memory-checking
tools such as valgrind. When valgrind's memcheck analyzes a
cairo-using program without a call to cairo_debug_reset_static_data(),
it will report all data reachable via cairo's static objects as
"still reachable". Calling cairo_debug_reset_static_data() just prior
to program termination will make it easier to get squeaky clean
reports from valgrind.
WARNING: It is only safe to call this function when there are no
active cairo objects remaining, (ie. the appropriate destroy
functions have been called as necessary). If there are active cairo
objects, this call is likely to cause a crash, (eg. an assertion
failure due to a hash table being destroyed when non-empty).

Obsolete functions. These definitions exist to coerce the compiler

The first set of REPLACED_BY functions is for functions whose names
have just been changed. So fixing these up is mechanical, (and
automated by means of the cairo/util/cairo-api-update script.
The second set of DEPRECATED_BY functions is for functions where
the replacement is used in a different way, (ie. different
arguments, multiple functions instead of one, etc). Fixing these up
will require a bit more work on the user's part, (and hopefully we
can get cairo-api-update to find these and print some guiding
information).

SECTION:cairo-device
@Title: cairo_device_t
@Short_Description: interface to underlying rendering system
@See_Also: #cairo_surface_t
Devices are the abstraction Cairo employs for the rendering system
used by a #cairo_surface_t. You can get the device of a surface using
cairo_surface_get_device().
Devices are created using custom functions specific to the rendering
system you want to use. See the documentation for the surface types
for those functions.
An important function that devices fulfill is sharing access to the
rendering system between Cairo and your application. If you want to
access a device directly that you used to draw to with Cairo, you must
first call cairo_device_flush() to ensure that Cairo finishes all
operations on the device and resets it to a clean state.
Cairo also provides the functions cairo_device_acquire() and
cairo_device_release() to synchronize access to the rendering system
in a multithreaded environment. This is done internally, but can also
be used by applications.
Putting this all together, a function that works with devices should
look something like this:
<informalexample><programlisting>
void
my_device_modifying_function (cairo_device_t *device)
{
cairo_status_t status;
// Ensure the device is properly reset
cairo_device_flush (device);
// Try to acquire the device
status = cairo_device_acquire (device);
if (status != CAIRO_STATUS_SUCCESS) {
printf ("Failed to acquire the device: %s\n", cairo_status_to_string (status));
return;
}
// Do the custom operations on the device here.
// But do not call any Cairo functions that might acquire devices.
// Release the device when done.
cairo_device_release (device);
}
</programlisting></informalexample>
<note><para>Please refer to the documentation of each backend for
additional usage requirements, guarantees provided, and
interactions with existing surface API of the device functions for
surfaces of that type.

We need to compare the x-coordinates of a pair of lines for a particular y,
without loss of precision.
The x-coordinate along an edge for a given y is:
X = A_x + (Y - A_y) * A_dx / A_dy
So the inequality we wish to test is:
A_x + (Y - A_y) * A_dx / A_dy ∘ B_x + (Y - B_y) * B_dx / B_dy,
where ∘ is our inequality operator.
By construction, we know that A_dy and B_dy (and (Y - A_y), (Y - B_y)) are
all positive, so we can rearrange it thus without causing a sign change:
A_dy * B_dy * (A_x - B_x) ∘ (Y - B_y) * B_dx * A_dy
- (Y - A_y) * A_dx * B_dy
Given the assumption that all the deltas fit within 32 bits, we can compute
this comparison directly using 128 bit arithmetic. For certain, but common,
input we can reduce this down to a single 32 bit compare by inspecting the
deltas.
(And put the burden of the work on developing fast 128 bit ops, which are
required throughout the tessellator.)

@Title: Error handling
@Short_Description: Decoding cairo's status
@See_Also: cairo_status(), cairo_surface_status(), cairo_pattern_status(),
cairo_font_face_status(), cairo_scaled_font_status(),
cairo_region_status()
Cairo uses a single status type to represent all kinds of errors. A status
value of %CAIRO_STATUS_SUCCESS represents no error and has an integer value
of zero. All other status values represent an error.
Cairo's error handling is designed to be easy to use and safe. All major
cairo objects <firstterm>retain</firstterm> an error status internally which
can be queried anytime by the users using cairo*_status() calls. In
the mean time, it is safe to call all cairo functions normally even if the
underlying object is in an error status. This means that no error handling
code is required before or after each individual cairo function call.

It is a toy API. It only offers very simple support for reading and
writing PNG files, which is sufficient for testing and
demonstration purposes. Applications which need more control over
the generated PNG file should access the pixel data directly, using
cairo_image_surface_get_data() or a backend-specific access
function, and process it with another library, e.g. gdk-pixbuf or

@Title: Raster Sources
@Short_Description: Supplying arbitrary image data
@See_Also: #cairo_pattern_t
The raster source provides the ability to supply arbitrary pixel data
whilst rendering. The pixels are queried at the time of rasterisation
by means of user callback functions, allowing for the ultimate
flexibility. For example, in handling compressed image sources, you
may keep a MRU cache of decompressed images and decompress sources on the
fly and discard old ones to conserve memory.
For the raster source to be effective, you must at least specify
the acquire and release callbacks which are used to retrieve the pixel
data for the region of interest and demark when it can be freed afterwards.
Other callbacks are provided for when the pattern is copied temporarily
during rasterisation, or more permanently as a snapshot in order to keep
the pixel data available for printing.

@Title: Recording Surfaces
@Short_Description: Records all drawing operations
@See_Also: #cairo_surface_t
A recording surface is a surface that records all drawing operations at
the highest level of the surface backend interface, (that is, the
level of paint, mask, stroke, fill, and show_text_glyphs). The recording
surface can then be "replayed" against any target surface by using it
as a source surface.
If you want to replay a surface so that the results in target will be
identical to the results that would have been obtained if the original
operations applied to the recording surface had instead been applied to the
target surface, you can use code like this:
<informalexample><programlisting>
cairo_t *cr;
cr = cairo_create (target);
cairo_set_source_surface (cr, recording_surface, 0.0, 0.0);
cairo_paint (cr);
cairo_destroy (cr);
</programlisting></informalexample>
A recording surface is logically unbounded, i.e. it has no implicit constraint
on the size of the drawing surface. However, in practice this is rarely
useful as you wish to replay against a particular target surface with
known bounds. For this case, it is more efficient to specify the target
extents to the recording surface upon creation.
The recording phase of the recording surface is careful to snapshot all
necessary objects (paths, patterns, etc.), in order to achieve
accurate replay. The efficiency of the recording surface could be
improved by improving the implementation of snapshot for the
various objects. For example, it would be nice to have a
copy-on-write implementation for _cairo_surface_snapshot.

XXX We currently have a confusing mix of boxes and rectangles as

represented by the coordinates of the upper left and lower right
corners, expressed in fixed point numbers. A #cairo_rectangle_int_t is
also a rectangular area, but represented by the upper left corner
and the width and the height, as integer numbers.
This function converts a #cairo_box_t to a #cairo_rectangle_int_t by
increasing the area to the nearest integer coordinates. We should
standardize on #cairo_rectangle_fixed_t and #cairo_rectangle_int_t, and
this function could be renamed to the more reasonable
_cairo_rectangle_fixed_round.

| cairo-scaled-font-private.h |
For most cairo objects, the rule for multiple threads is that
the user is responsible for any locking if the same object is
manipulated from multiple threads simultaneously.
However, with the caching that cairo does for scaled fonts, a
user can easily end up with the same cairo_scaled_font object
being manipulated from multiple threads without the user ever
being aware of this, (and in fact, unable to control it).
So, as a special exception, the cairo implementation takes care
of all locking needed for cairo_scaled_font_t. Most of what is
in the scaled font is immutable, (which is what allows for the
sharing in the first place). The things that are modified and
the locks protecting them are as follows:
1. The reference count (scaled_font->ref_count)
Modifications to the reference count are protected by the
_cairo_scaled_font_map_mutex. This is because the reference
count of a scaled font is intimately related with the font
map itself, (and the magic holdovers array).
2. The cache of glyphs (scaled_font->glyphs)
3. The backend private data (scaled_font->surface_backend,
scaled_font->surface_private)
Modifications to these fields are protected with locks on
scaled_font->mutex in the generic scaled_font code.

subsets with glyph indices packed into the range
[0 .. max_glyphs_per_subset).

angular difference that is strictly less than pi). To break ties

Also, all slope vectors with both dx==0 and dy==0 are considered
equal and more positive than any non-zero vector.

@Title: cairo_surface_t
@Short_Description: Base class for surfaces
@See_Also: #cairo_t, #cairo_pattern_t
#cairo_surface_t is the abstract type representing all different drawing
targets that cairo can render to. The actual drawings are
performed using a cairo <firstterm>context</firstterm>.
A cairo surface is created by using <firstterm>backend</firstterm>-specific
constructors, typically of the form
<function>cairo_<emphasis>backend</emphasis>_surface_create(<!-- -->)</function>.
Most surface types allow accessing the surface without using Cairo
functions. If you do this, keep in mind that it is mandatory that you call
cairo_surface_flush() before reading from or writing to the surface and that
you must use cairo_surface_mark_dirty() after modifying it.
<example>
<title>Directly modifying an image surface</title>
<programlisting>
void
modify_image_surface (cairo_surface_t *surface)
{
unsigned char *data;
int width, height, stride;
// flush to ensure all writing to the image was done
cairo_surface_flush (surface);
// modify the image
data = cairo_image_surface_get_data (surface);
width = cairo_image_surface_get_width (surface);
height = cairo_image_surface_get_height (surface);
stride = cairo_image_surface_get_stride (surface);
modify_image_data (data, width, height, stride);
// mark the image dirty so Cairo clears its caches.
cairo_surface_mark_dirty (surface);
}
</programlisting>
</example>
Note that for other surface types it might be necessary to acquire the
surface's device first. See cairo_device_acquire() for a discussion of
devices.

The structs defined here should strictly follow the TrueType
specification and not be padded. We use only 16-bit integer
in their definition to guarantee that. The fields of type
"FIXED" in the TT spec are broken into two *_1 and *_2 16-bit
parts, and 64-bit members are broken into four.
The test truetype-tables in the test suite makes sure that
these tables have the right size. Please update that test
if you add new tables/structs that should be packed.

@Title: cairo_t
@Short_Description: The cairo drawing context
@See_Also: #cairo_surface_t
#cairo_t is the main object used when drawing with cairo. To
draw with cairo, you create a #cairo_t, set the target surface,
and drawing options for the #cairo_t, create shapes with
functions like cairo_move_to() and cairo_line_to(), and then
draw shapes with cairo_stroke() or cairo_fill().
#cairo_t<!-- -->'s can be pushed to a stack via cairo_save().
They may then safely be changed, without losing the current state.
Use cairo_restore() to restore to the saved state.

This isn't a "real" surface, but just something to be used by the
test suite to help exercise the paginated-surface paths in cairo.
The defining feature of this backend is that it uses a paginated
surface to record all operations, and then replays everything to an
image surface.
It's possible that this code might serve as a good starting point
for someone working on bringing up a new paginated-surface-based
backend.
