ae5575b342 Fix gradients rendering and destructor crashes.
This changes binds all textures to GL_TEXTURE0, this will have
to be changed when combining shader capabilities.

7fac2e1833 Add plumbing to support gradients in OpenGL renderer.
The LinearGradient class keeps a copy of the various parameters that
define the gradient. The copies are native arrays to avoid copying
Java arrays on every draw call. The gradient code path is implemented
until OpenGLRenderer::drawRect() (see TODO.) The actual gradient
implementation will be added in a latter change.

079ba2c85b Improve clip support (add intersect, union and replace.)
This change also modifies the way the clip is stored. The clip is now
always stored in screen-space coordinates.

d27977d1a9 Add support for BitmapShader.
This change also fixes an issue with the clip and layers.

3d58c03de0 Do not apply transforms when using drawColor().
This fixes an issue in the way the clip transformations were applied.

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.)

dda570201a Add a layer (FBO) cache.
The cache is used to draw layers so that a new
texture does not have to be recreated every time
a call to saveLayer() happens.

The FBO cache used a KeyedVector, which is a bad
idea. The cache should be able to store several
FBOs of the same size (this happens a lot during
scrolling with fading edges for instance.) This
will be changed in a future CL.

f86ef57f8b Don't use full screen FBOs, this dramatically increase performance.
The next step will be to add an FBO cache to avoid churning memory on every
frame we draw. This change also adds support for drawBitmap(Bitmap, Matrix, Paint).

d55a86120d Add support for saveLayer().
saveLayer() is affected by the paint's alpha and xfermode.

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.
