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.

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.

This change detects empty quads in 9patches and removes them from
the mesh to avoid unnecessary blending.
Change-Id: I4500566fb4cb6845d64dcb59b522c0be7a0ec704
Add a glGetError() check on every frame
Don't attempt to create textures larger than the maximum size allowed

The implementation is simple but tricky. Leave explanations to my
future self so that I don't invent a time machine to come back to
now and slap my self.
This change also simplifies the way the GL blending function is
chosen when compositing a layer. It reuses existing OpenGLRenderer
APIs and is easier to understand.

This adds the ability to blend with the framebuffer using Darken,
Lighten, Add, Multiply, Overlay and Screen.

Rendering is implementing by rasterizing the paths into A8 textures.
This cna be extremely inefficient if the path changes often.

With this change, Skia shaders can easily be applied to any mesh. This change also
supports ComposeShader. For instance, this can be used to blend a gradient and a
bitmap togehter and paint a string of text with the result.

This changes binds all textures to GL_TEXTURE0, this will have
to be changed when combining shader capabilities.
Change-Id: I02df4f5ba41e9b01ffa52fd7c26b41477c7ed18f
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.
Change-Id: I903a11a070c0eb9cc8850a60ef305751e5b47234
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.

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.
Change-Id: I885afc076bb6cef8cd3962ae21a086fa6a03bf96
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.
Change-Id: I9300d250ef5e2e9c2e097c3116ee71dfc9d752d8
The renderer is still changing textures' wrap modes every time, this will require
a latter optimization.
Change-Id: I3eb92cb8c886c4a692b7f0ca759911f9371d4d2c
This change also modifies the way the clip is stored. The clip is now
always stored in screen-space coordinates.
Change-Id: I96375784d82dfe975bc6477a159e6866e7052487
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.
