889f8d1403 Moved all the rendering code to the new shader generator.
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.

ac670c0433 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.

f9764a4f53 Add program for linear gradient.
This change adds a new DrawLinearGradientProgram class to enable the drawing
of linear gradients. Two new vertex and fragment shaders are introduced,
based on DrawTextureProgram's shaders.

6926c72e25 Correctly support pre-multiplied alpha, optimizations, more stuff.
Add support for the following drawing functions:
- drawBitmap(int[]...)
- drawPaint()

Optimizes shader state changes by enabling/disabling attribute arrays
only when needed.

Adds quick rejects when drawing trivial shapes to avoid unnecessary
OpenGL operations.

260e102162 Optimize shader binding changes.
This change also cleans up the internal API a little bit by using mat4
everywhere instead of float[16] (for the ortho matrix for instance.)

5cbbce5357 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.
