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.
