For versions of these calls that take additoinal args and value pairs we currently just drop them
and report only the name. Since ATrace is a simple push and pop system (all traces are fully
nested), if using BEGIN and END you should also make sure your calls are properly nested (i.e. if
startA is before startB, then endB is before endA).

The decal_ functions require that

In addition, we use SkFractionalInt to keep more fractional precision than
just SkFixed, so we will abort the decal_ call if dx is very small, since
the decal_ function just operates on SkFixed. If that were changed, we could
skip the very_small test here.

| SkBlurEngine.cpp |
|
59575 |
| SkBlurEngine.h |
SkBlurEngine is a backend-agnostic provider of blur algorithms. Each Skia backend defines a blur
engine with a set of supported algorithms and/or implementations. A given implementation may be
optimized for a particular color type, sigma range, or available hardware. Each engine and its
algorithms are assumed to operate only on SkImages corresponding to its Skia backend, and will
produce output SkImages of the same type.
Algorithms are allowed to specify a maximum supported sigma. If the desired sigma is higher than
this, the input image and output region must be downscaled by the caller before invoking the
algorithm. This is to provide the most flexibility for input representation (e.g. directly
rasterize at half resolution or apply deferred filter effects during the first downsample pass).
skif::FilterResult::Builder::blur() is a convenient wrapper around the blur engine and
automatically handles resizing.

Attaching a data to to a SkResourceCache (only one at a time) enables the data to be
unlocked when the cache is the only owner, thus freeing it to be purged (assuming the
data is backed by a SkDiscardableMemory).
When attached, it also automatically attempts to "lock" the data when the first client
ref's the data (typically from a find(key, visitor) call).
Thus the data will always be "locked" when a non-cache has a ref on it (whether or not
the lock succeeded to recover the memory -- check data() to see if it is nullptr).

SkDevice is the internal API and implementation that SkCanvas will use to perform rendering and
implement the saveLayer abstraction. A device wraps some pixel allocation (for non-document based
devices) or wraps some other container that stores rendering operations. The drawing operations
perform equivalently to their corresponding functions in SkCanvas except that the canvas is
responsible for all SkImageFilters. An image filter is applied by automatically creating a layer,
drawing the filter-less paint into the layer, and then evaluating the filter on the layer's
image.
Each layer in an SkCanvas stack is represented by an SkDevice instance that was created by the
parent SkDevice (up to the canvas's base device). In most cases these devices will be pixel
aligned with one another but may differ in size based on the known extent of the active clip. In
complex image filtering scenarios, they may not be axis aligned, although the effective pixel
size should remain approximately equal across all devices in a canvas.
While SkCanvas manages a single stack of layers and canvas transforms, SkDevice does not have a
stack of transforms. Instead, it has a single active transform that is modified as needed by
SkCanvas. However, SkDevices are the means by which SkCanvas manages the clip stack because each
layer's clip stack starts anew (although the layer's results are then clipped by its parent's
stack when it is restored).

To save on mallocs, we allow a flag that tells us that srcPath is
mutable, so that we don't have to make copies of it as we transform it.
If prePathMatrix is not null, it should logically be applied before any
stroking or other effects. If there are no effects on the paint that
affect the geometry/rasterization, then the pre matrix can just be
pre-concated with the current matrix.
|
6238 |
| SkDrawProcs.h |
If the current paint is set to stroke and the stroke-width when applied to
the matrix is <= 1.0, then this returns true, and sets coverage (simulating
a stroke by drawing a hairline with partial coverage). If any of these
conditions are false, then this returns false and coverage is ignored.

In setLine, setQuadratic, setCubic, the first thing we do is to convert
the points into FDot6. This is modulated by the shift parameter, which
will either be 0, or something like 2 for antialiasing.
In the float case, we want to turn the float into .6 by saying pt * 64,
or pt * 256 for antialiasing. This is implemented as 1 << (shift + 6).
In the fixed case, we want to turn the fixed into .6 by saying pt >> 10,
or pt >> 8 for antialiasing. This is implemented as pt >> (10 - shift).

This is the size we use when we ask for a glyph's path. We then
post-transform it as we draw to match the request.
This is done to try to re-use cache entries for the path.
This value is somewhat arbitrary. In theory, it could be 1, since
we store paths as floats. However, we get the path from the font
scaler, and it may represent its paths as fixed-point (or 26.6),
so we shouldn't ask for something too big (might overflow 16.16)
or too small (underflow 26.6).
This value could track kMaxSizeForGlyphCache, assuming the above
constraints, but since we ask for unhinted paths, the two values
need not match per-se.

Examines the bitmap to decide if it can share the existing pixelRef, or
if it needs to make a deep-copy of the pixels.
The bitmap's pixelref will be shared if either the bitmap is marked as
immutable, or CopyPixelsMode allows it. Shared pixel refs are also
locked when kLocked_SharedPixelRefMode is specified.
Passing kLocked_SharedPixelRefMode allows the image's peekPixels() method
to succeed, but it will force any lazy decodes/generators to execute if
they exist on the pixelref.
It is illegal to call this with a texture-backed bitmap.
If the bitmap's colortype cannot be converted into a corresponding
SkImageInfo, or the bitmap's pixels cannot be accessed, this will return
nullptr.

|
2781 |
| SkOpts.h |
SkOpts (short for SkOptimizations) is a mechanism where we can ship with multiple implementations
of a set of functions and dynamically choose the best one at runtime (e.g. the call to
SkGraphics::Init(), which calls SkOpts::Init()) depending on the detected CPU features. This is
also referred to as having "specializations" of a given function.
For example, Skia might be compiled to support CPUs that only have the sse2 instruction set
(https://en.wikipedia.org/wiki/X86_instruction_listings#SSE2_instructions)
but may be run on a more modern CPU that supports AVX2 instructions.
(https://en.wikipedia.org/wiki/Advanced_Vector_Extensions)
SkOpts allow Skia to have two versions of a row-blitting function, one that uses normal C++
code (e.g. loops, scalar integer math) and one that makes use of the AVX2 vector types and
intrinsic functions. This function is declared here in the SkOpts namespace, and then the
implementation (see SkOpts.cpp) is deferred to a function of the same name in the sse2::
namespace (the minimum Skia is compiled with) using DEFINE_DEFAULT.
All implementations of this blit function are done in a header file file in //src/opts
(e.g. //src/opts/SkBlitRow_opts.h). ifdefs guard each of the implementations, such that only
one implementation is possible for a given SK_CPU_SSE_LEVEL. This header will be compiled
*multiple* times with a different SK_CPU_SSE_LEVEL each compilation.
Each CPU instruction set that we want specializations for has a .cpp file in //src/opts which
defines an Init() function that replaces the function pointers in the SkOpts namespace with the
ones from the specialized namespace (e.g. hsw::). These .cpp files don't implement the
specializations, they just refer to the specialization created in the header files (e.g.
SkBlitRow_opts.h).
At compile time:
- SkOpts.cpp is compiled with the minimum CPU level (e.g. SSE2). Because this
file includes all the headers in //src/opts/, those headers add "the default implementation"
of all their functions to the SK_OPTS_NS namespace (e.g. sse2::blit_row_color32).
- Each of the specialized .cpp files in //src/opts/ are compiled with their respective
compiler flags. Because the specialized .cpp file includes the headers that implement the
functions using intrinsics or other CPU-specific code, those specialized functions end up
in the specialized namespace, e.g. (hsw::blit_row_color32).
At link time, the default implementations and all specializations of all SkOpts functions are
included in the resulting library/binary file.
At runtime, SkOpts::Init() will run the appropriate Init functions that the current CPU level
supports specializations for (e.g. Init_hsw, Init_ssse3). Note multiple Init functions can
be called as CPU instruction sets are typically super sets of older instruction sets

| SkPictureRecord.cpp |
No need for a (potentially very big) layer which we don't actually need
at this time (and may not be able to afford since during record our

Write the 'drawType' operation and chunk size to the skp. 'size'
can potentially be increased if the chunk size needs its own storage
location (i.e., it overflows 24 bits).
Returns the start offset of the chunk. This is the location at which
the opcode & size are stored.
TODO: since we are handing the size into here we could call reserve
and then return a pointer to the memory storage. This could decrease
allocation overhead but could lead to more wasted space (the tail
end of blocks could go unused). Possibly add a second addDraw that
operates in this manner.

SkRasterPipeline provides a cheap way to chain together a pixel processing pipeline.
It's particularly designed for situations where the potential pipeline is extremely
combinatoric: {N dst formats} x {M source formats} x {K mask formats} x {C transfer modes} ...
No one wants to write specialized routines for all those combinations, and if we did, we'd
end up bloating our code size dramatically. SkRasterPipeline stages can be chained together
at runtime, so we can scale this problem linearly rather than combinatorically.
Each stage is represented by a function conforming to a common interface and by an
arbitrary context pointer. The stage function arguments and calling convention are
designed to maximize the amount of data we can pass along the pipeline cheaply, and
vary depending on CPU feature detection.

Scanline mimics a row in the region, nearly. A row in a region is:
[Bottom IntervalCount [L R]... Sentinel]
while a Scanline is
[LastY XCount [L R]... uninitialized]
The two are the same length (which is good), but we have to transmute
the scanline a little when we convert it to a region-row.
Potentially we could recode this to exactly match the row format, in
which case copyToRgn() could be a single memcpy. Not sure that is worth
the effort.

An R-Tree implementation. In short, it is a balanced n-ary tree containing a hierarchy of

It only supports bulk-loading, i.e. creation from a batch of bounding rectangles.
This performs a bottom-up bulk load using the STR (sort-tile-recursive) algorithm.
TODO: Experiment with other bulk-load algorithms (in particular the Hilbert pack variant,
which groups rects by position on the Hilbert curve, is probably worth a look). There also
exist top-down bulk load variants (VAMSplit, TopDownGreedy, etc).

| SkScan_AAAPath.cpp |
The following is a high-level overview of our analytic anti-aliasing
algorithm. We consider a path as a collection of line segments, as
quadratic/cubic curves are converted to small line segments. Without loss of
generality, let's assume that the draw region is [0, W] x [0, H].
Our algorithm is based on horizontal scan lines (y = c_i) as the previous
sampling-based algorithm did. However, our algorithm uses non-equal-spaced
scan lines, while the previous method always uses equal-spaced scan lines,
such as (y = 1/2 + 0, 1/2 + 1, 1/2 + 2, ...) in the previous non-AA algorithm,
and (y = 1/8 + 1/4, 1/8 + 2/4, 1/8 + 3/4, ...) in the previous
16-supersampling AA algorithm.
Our algorithm contains scan lines y = c_i for c_i that is either:
1. an integer between [0, H]
2. the y value of a line segment endpoint
3. the y value of an intersection of two line segments
For two consecutive scan lines y = c_i, y = c_{i+1}, we analytically computes
the coverage of this horizontal strip of our path on each pixel. This can be
done very efficiently because the strip of our path now only consists of
trapezoids whose top and bottom edges are y = c_i, y = c_{i+1} (this includes
rectangles and triangles as special cases).
We now describe how the coverage of single pixel is computed against such a
trapezoid. That coverage is essentially the intersection area of a rectangle
(e.g., [0, 1] x [c_i, c_{i+1}]) and our trapezoid. However, that intersection
could be complicated, as shown in the example region A below:
+-----------\----+
| \ C|
| \ |
\ \ |
|\ A \|
| \ \
| \ |
| B \ |
+----\-----------+
However, we don't have to compute the area of A directly. Instead, we can
compute the excluded area, which are B and C, quite easily, because they're
just triangles. In fact, we can prove that an excluded region (take B as an
example) is either itself a simple trapezoid (including rectangles, triangles,
and empty regions), or its opposite (the opposite of B is A + C) is a simple
trapezoid. In any case, we can compute its area efficiently.
In summary, our algorithm has a higher quality because it generates ground-
truth coverages analytically. It is also faster because it has much fewer
unnessasary horizontal scan lines. For example, given a triangle path, the
number of scan lines in our algorithm is only about 3 + H while the
16-supersampling algorithm has about 4H scan lines.
|
70764 |
| SkScan_Antihair.cpp |
Our attempt to compute the worst case "bounds" for the horizontal and
vertical cases has some numerical bug in it, and we sometimes undervalue
our extends. The bug is that when this happens, we will set the clip to
nullptr (for speed), and thus draw outside of the clip by a pixel, which might
only look bad, but it might also access memory outside of the valid range
allcoated for the device bitmap.
This define enables our fix to outset our "bounds" by 1, thus avoiding the
chance of the bug, but at the cost of sometimes taking the rectblitter
case (i.e. not setting the clip to nullptr) when we might not actually need
to. If we can improve/fix the actual calculations, then we can remove this
step.

| SkVerticesPriv.h |
Class that adds methods to SkVertices that are only intended for use internal to Skia.
This class is purely a privileged window into SkVertices. It should never have additional
data members or virtual methods. |

| SkVertState.h |
\struct VertState
This is a helper for drawVertices(). It is used to iterate over the triangles
that are to be rendered based on an SkCanvas::VertexMode and (optionally) an
index array. It does not copy the index array and the client must ensure it
remains valid for the lifetime of the VertState object.

| SkWriter32.cpp |
|
2221 |
| SkWriter32.h |
The caller can specify an initial block of storage, which the caller manages.
SkWriter32 will try to back reserve and write calls with this external storage until the
first time an allocation doesn't fit. From then it will use dynamically allocated storage.
This used to be optional behavior, but pipe now relies on it.

| SkYUVAInfo.cpp |
|
13968 |
| SkYUVAInfoLocation.h |
The location of Y, U, V, or A values within the planes described by SkYUVAInfo. Computed from a
SkYUVAInfo and the set of channels present in a set of pixmaps/textures.

| SkYUVPlanesCache.h |
On success, return a ref to the SkCachedData that holds the pixel data. The SkYUVAPixmaps
contains a description of the YUVA data and has a SkPixmap for each plane that points
into the SkCachedData.
On failure, return nullptr.
