Add
Multiply
Screen
Overlay
Darken
Lighten

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

Hardware acceleration can now be enabled/disabled locally on each activity
declared in the manifest. It can also be enabled/disabled directly on a
window through the WindowManager.LayoutParams.

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.

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
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.

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).

The blending modes are currently hooked up only when drawing filled rects but the
code is reusable for other primitives. This will allow implementation of saveLayer().
This method is required to support the fade effects used throughout the standard
Android UI.

Even though there's an implementation for textured rects, drawBitmap() is not
hooked up yet as it will require a good texture cache.
This method is implemented using FBOs. There's currently an issue either in the
driver or in the Canvas renderer that forces the FBO to be fullscreen, which is
extremely expensive and yields terrible performance.

The OpenGL ES 2.0 renderer can now draw colored rectangles. At least there's
something on screen now.
Change-Id: I80a13ccc1dd56784edf74f2670a364f30700234a
Drawing two rectangles one after the other discards the second one because of
Z buffering issues. This will be fixed in another changelist.

This is the initial checkin to setup the library and turn on OEGL ES 2.0
in ViewRoot, not a functional renderer.

Bitmap.getGenerationId() can be used by caches to find out if a Bitmap has been
modified. This simply exposes an existing Skia API.
This change also adds a small test app for Canvas hardware acceleration. The new
Bitmap API is required to implement a texture cache.
