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.

Bug #3282805
This bug was introduced with a previous refactoring. This also fixes
issues with setting the alpha when drawing bitmaps.
Change-Id: Id47641d26a4536c7e540041f92243bf6db9fc96d
This is the first step of the refactoring:
- drawColorRect
- drawTextureMesh
Remaining methods to refactor:
- setupTextureAlpha8
- drawPath
- setupShadow
- drawText
- drawLines
- composeLayerRegion

Bug #3179882
Resources were freed following garbage collections on a worker thread.
This worker thread had no EGL context, which would cause the renderer
to incorrectly assume that the memory was liberated.

GL renderer was not initializing scissor correctly for translucent
surfaces, resulting in invisible window backgrounds in some cases
like fading popup windows

Lines were not drawing in Calendar because they were getting clipped
by the previous clip rectangle. This change simply updates the scissor
as needed. This change also reduces the number of state changes in GL.

drawColor() was not calling quickReject because it fills the clip region
and thus always passes the test. However, quickReject also checks whether
the current layer is invisible. drawColor() now performs the same check
and avoid drawing inside an invisible layer.

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.

This change batches calls to glScissor() and removes extra GL
queries and glActiveTexture() calls.

A change was made earlier in the renderer to not snap the current clip rect
on every clip operation. The clip rect must not be snapped to pixel boundaries
before being used for pixel precision operations. Some operations were doing
this correctly, others were not. For instance, a layer was always created by
rounding to the correct pixels, but composing a layer was done with a non
rounded clip, thus resulting in slightly odd behaviors.

The local clip rect could be off by one pixel when a 3D transform
was applied to a text primitive. This would cause small rendering
glitches in Launcher in particular.

Don't clear the entire texture when we use textures that are bigger
than the layer itself. This will save time during the glClear() calls.

This change detects empty quads in 9patches and removes them from
the mesh to avoid unnecessary blending.
