2. Disable an early and trivial clip optimization in font renderer
when a perspective transformation is used on the Canvas

d3efd6920e64d0207a0655640297d87d4937ee27 07-May-2012 Chet Haase <chet@google.com> Fix issue where scale-animating text would jump temporarily a few pixels

Some logic in the native matrix code would determine that a matrix was
'pureTranslate' based on the scale values of a matrix being close-enough to 1,
which was within a very small epsilon. This works in general, because screen space
coordinates make that epsilon value irrelevant, so close-enough really is close-enough.

However, TextView, when centering text, works in a coordinate system that is quite
huge, with left/right values about 500,000. These numbers multiplied times that small
epsilon value would give a result that was significant, and would cause a miscalculation
of up to 4-5 pixels, causing the snap that we'd see for a couple of frames as the
scale got "close enough" to 1.

The fix is to remove the optimization of "close enough". What we really need the matrix to
do is to identify itself as being translate-only when no scale as been set (which is the
default). For the purposes of that check, it is good enough to simply check the values against
1 directly. Similarly, the bounds-check logic needs to check against 0 and 1 directly.

The generator supports features that are not yet implement in the
renderer: color matrix, lighting, porterduff color blending and
composite shaders.

This change also adds support for repeated/mirrored non-power of 2
bitmap shaders.

This change also refactors the code base a bit by moving classes out of
OpenGLRenderer into separate headers/implementations. This makes the code
more manageable.

This change also adds documentation for implementation methods. The
undocumented methods are simply Skia's Canvas methods.

Even though there's an implementation for textured rects, drawBitmap() is not
hooked up yet as it will require a good texture cache.

This method is implemented using FBOs. There's currently an issue either in the
driver or in the Canvas renderer that forces the FBO to be fullscreen, which is
extremely expensive and yields terrible performance.

f6a11b8a9e25ff9861bbba19251bea84d8a5daf2 24-Jun-2010 Romain Guy <romainguy@google.com> Add support for transformations.

This change adds partial support for the following transforms:
- scale()
- translate()
- rotate()
- setMatrix()
- getMatrix()

The transform is stored in a snapshot and saved/restored as needed.
The transform is currently not applied to the clip rect and is not
mapped to the vertex shader.
