BaseRect.h 
Rectangles have two interpretations: a set of (zerosize) points,
and a rectangular area of the plane. Most rectangle operations behave
the same no matter what interpretation is being used, but some operations
differ:
 Equality tests behave differently. When a rectangle represents an area,
all zerowidth and zeroheight rectangles are equal to each other since they
represent the empty area. But when a rectangle represents a set of
mathematical points, zerowidth and zeroheight rectangles can be unequal.
 The union operation can behave differently. When rectangles represent
areas, taking the union of a zerowidth or zeroheight rectangle with
another rectangle can just ignore the empty rectangle. But when rectangles
represent sets of mathematical points, we may need to extend the latter
rectangle to include the points of a zerowidth or zeroheight rectangle.
To ensure that these interpretations are explicitly disambiguated, we
deny access to the == and != operators and require use of IsEqualEdges and
IsEqualInterior instead. Similarly we provide separate Union and UnionEdges
methods.

Blur.cpp 
Helper function to process each row of the box blur.
It takes care of transposing the data on input or output depending
on whether we intend a horizontal or vertical blur, and whether we're
reading from the initial source or writing to the final destination.
It allows starting or ending anywhere within the row to accomodate
a skip rect.

32223 
Blur.h 
Implementation of a triple box blur approximation of a Gaussian blur.
A Gaussian blur is good for blurring because, when done independently
in the horizontal and vertical directions, it matches the result that
would be obtained using a different (rotated) set of axes. A triple
box blur is a very close approximation of a Gaussian.
This is a "service" class; the constructors set up all the information
based on the values and compute the minimum size for an 8bit alpha
channel context.
The callers are responsible for creating and managing the backing surface
and passing the pointer to the data to the Blur() method. This class does
not retain the pointer to the data outside of the Blur() call.
A spread N makes each output pixel the maximum value of all source
pixels within a square of side length 2N+1 centered on the output pixel.

DrawTargetCairo.cpp 
Clamp r to (0,0) (2^23,2^23)
these are to be device coordinates.
Returns false if the rectangle is completely out of bounds,
true otherwise.
This function assumes that it will be called with a rectangle being
drawn into a surface with an identity transformation matrix; that
is, anything above or to the left of (0,0) will be offscreen.
First it checks if the rectangle is entirely beyond
CAIRO_COORD_MAX; if so, it can't ever appear on the screen 
false is returned.
Then it shifts any rectangles with x/y < 0 so that x and y are = 0,
and adjusts the width and height appropriately. For example, a
rectangle from (0,5) with dimensions (5,10) will become a
rectangle from (0,0) with dimensions (5,5).
If after negative x/y adjustment to 0, either the width or height
is negative, then the rectangle is completely offscreen, and
nothing is drawn  false is returned.
Finally, if x+width or y+height are greater than CAIRO_COORD_MAX,
the width and height are clamped such x+width or y+height are equal
to CAIRO_COORD_MAX, and true is returned.

ImageScaling.cpp 
The surface we sample from might not be even sized, if it's not we will
ignore the last row/column. This means we lose some data but it keeps the
code very simple. There's also no perfect answer that provides a better
solution.

8022 
ImageScaling.h 

3079 
ImageScalingSSE2.cpp 
The functions below use the following system for averaging 4 pixels:
The first observation is that a halfadder is implemented as follows:
R = S + 2C or in the case of a and b (a ^ b) + ((a & b) << 1);
This can be trivially extended to three pixels by observaring that when
doing (a ^ b ^ c) as the sum, the carry is simply the bitwiseor of the
carries of the individual numbers, since the sum of 3 bits can only ever
have a carry of one.
We then observe that the average is then ((carry << 1) + sum) >> 1, or,
assuming eliminating overflows and underflows, carry + (sum >> 1).
We now average our existing sum with the fourth number, so we get:
sum2 = (sum + d) >> 1 or (sum >> 1) + (d >> 1).
We now observe that our sum has been moved into place relative to the
carry, so we can now average with the carry to get the final 4 input
average: avg = (sum2 + carry) >> 1;
Or to reverse the proof:
avg = ((sum >> 1) + carry + d >> 1) >> 1
avg = ((a + b + c) >> 1 + d >> 1) >> 1
avg = ((a + b + c + d) >> 2)
An additional fact used in the SSE versions is the concept that we can
trivially convert a rounded average to a truncated average:
We have:
f(a, b) = (a + b + 1) >> 1
And want:
g(a, b) = (a + b) >> 1
Observe:
~f(~a, ~b) == ~((~a + ~b + 1) >> 1)
== ~((a  1 + b  1 + 1) >> 1)
== ~((a  1 + b) >> 1)
== ~(((a + b)  1) >> 1)
== ~((~(a + b)) >> 1)
== (a + b) >> 1
== g(a, b)

PatternHelpers.h 
This class is used to allow general pattern creation functions to return
any type of pattern via an outparamater without allocating a pattern
instance on the freestore (an instance of this class being created on the
stack before passing it in to the creation function). Without this class
writing pattern creation functions would be a pain since Pattern objects are
not reference counted, making lifetime management of instances created on
the freestore and returned from a creation function hazardous. Besides
that, in the case that ColorPattern's are expected to be common, it is
particularly desirable to avoid the overhead of allocating on the
freestore.

The API is currently very barebones; it may be extended as needed.

Scale.h 
Scale an image using a highquality filter.
Synchronously scales an image and writes the output to the destination in

Returns true if scaling was successful, and false otherwise. Currently, this
function is implemented using Skia. If Skia is not enabled when building,
calling this function will always return false.
IMPLEMTATION NOTES:
This API is not currently easily hardware acceleratable. A better API might
take a SourceSurface and return a SourceSurface; the Direct2D backend, for
example, could simply set a status bit on a copy of the image, and use
Direct2D's highquality scaler at draw time.
