Make gradients beautiful again
Bug #7239634
This change passes two matrices to the vertex shader instead of one.
We used to compute the final MVP matrix on the CPU to minimize the
number of operations in the vertex shaders. Shader compilers are
however smart enough to perform this optimization for us. Since we
need the MV matrix to properly compute gradients dithering, this
change splits the MVP matrix into two. This has the advantage of
removing one matrix multiplication per drawing operation on the
CPU.
The SGX 540 shader compiler produces the same number of instructions
in both cases. There is no penalty hit with having two matrices
instead of one. We also send so few vertices per frame that it
does not matter very much.

Fix modulation and gamma correction issues
Modulation is normally enabled in a shader when drawing with an alpha
mask (A8 texture.) Modulation is used to do one of two things:
- Colorize the primitive (to draw text in red for instance)
- Apply extra translucency (50% translucent circle filled with a bitmap)
The current implementation has four issues:
1. Unnecessary work is performed by assigning the modulation color
to vec4 fragColor early in the shader
2. The modulation color's alpha is applied twice when the primitive
is drawn with an SkShader
3. The decision to modulate is wrong and triggers when any of the
RGB channels is < 1.0. Only the alpha channel needs to be taken
into account to make the decision
4. Gamma correction is not applied properly
This change addresses all four issues above.

Varying-based AA rect drawing
Instead of calculating opacity from relative position in the shader, use a
shader varying to do this computation for us.
bug:5045101
Also adds a test to HwAccelerationTest to show incorrect antialiasing in
scaled drawAARect / boundarySize calculation.

Fix various hw-accelerated line/point bugs
All accelerated lines are now rendered as quads. Hairlines used to
be rendered as GL_LINES, but these lines don't render the same as our
non-accelerated lines, so we're using quads for everything. Also, fixed
a bug in the way that we were offsetting quads (and not offseting points)
to ensure that our lines/points actuall start on the same pixels as
Skia's.

renderer: color matrix, lighting, porterduff color blending and
composite shaders.
This change also adds support for repeated/mirrored non-power of 2
bitmap shaders.

Generate shaders to cover all possible cases.
With this change, all the vertex and fragment shaders used by the GL
renderer are now generated based on a program description supplied
by the caller. This allows the renderer to generate a large number
of shaders without having to write all the possible combinations by
hand. The generated shaders are stored in a program cache.

Reduced the complexity of layers composition.
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.
