f219da5e32 Don't blend transparent pixels when rendering layers.
With this change, the rendere keeps track of what regions are rendered into
and generates a mesh that matches these regions exactly. The mesh is used
to composite the layer on screen.

171c592f0b New layers API for Views.
This API can be used to back a view and its children with either a
software layer (bitmap) or hardware layer (FBO). Layers have
various usages, including color filtering and performance
improvements during animations.

5b3b35296e Optimize FBO drawing with regions.
This optimization is currently disabled until Launcher is
modified to take advantage of it. The optimization can be
enabled by turning on RENDER_LAYERS_AS_REGIONS in the
OpenGLRenderer.h file.

eb99356a05 Optimize saveLayer() when the clip flag is set.
This speeds up applications, especially Launcher.

0bb5667b4e Fix INVALID_OPERATION error with layers rendering.
This change is a workaround for a driver bug that causes an INVALID_OPERATION
to be thrown on every glCopyTexSubImage() call. This change also adds a new
test for gradients local matrices.

6c81893c62 Simpler way to deal with the FBO multi-cache.
This change removes the need for the SortedList and instead just
add a generated id to each FBO stored in the cache. This is an
artificial way to store several FBOs with the same dimensions.

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.
