Pack preloaded framework assets in a texture atlas
When the Android runtime starts, the system preloads a series of assets
in the Zygote process. These assets are shared across all processes.
Unfortunately, each one of these assets is later uploaded in its own
OpenGL texture, once per process. This wastes memory and generates
unnecessary OpenGL state changes.
This CL introduces an asset server that provides an atlas to all processes.
Note: bitmaps used by skia shaders are *not* sampled from the atlas.
It's an uncommon use case and would require extra texture transforms
in the GL shaders.
WHAT IS THE ASSETS ATLAS
The "assets atlas" is a single, shareable graphic buffer that contains
all the system's preloaded bitmap drawables (this includes 9-patches.)
The atlas is made of two distinct objects: the graphic buffer that
contains the actual pixels and the map which indicates where each
preloaded bitmap can be found in the atlas (essentially a pair of
x and y coordinates.)
HOW IS THE ASSETS ATLAS GENERATED
Because we need to support a wide variety of devices and because it
is easy to change the list of preloaded drawables, the atlas is
generated at runtime, during the startup phase of the system process.
There are several steps that lead to the atlas generation:
1. If the device is booting for the first time, or if the device was
updated, we need to find the best atlas configuration. To do so,
the atlas service tries a number of width, height and algorithm
variations that allows us to pack as many assets as possible while
using as little memory as possible. Once a best configuration is found,
it gets written to disk in /data/system/framework_atlas
2. Given a best configuration (algorithm variant, dimensions and
number of bitmaps that can be packed in the atlas), the atlas service
packs all the preloaded bitmaps into a single graphic buffer object.
3. The packing is done using Skia in a temporary native bitmap. The
Skia bitmap is then copied into the graphic buffer using OpenGL ES
to benefit from texture swizzling.
HOW PROCESSES USE THE ATLAS
Whenever a process' hardware renderer initializes its EGL context,
it queries the atlas service for the graphic buffer and the map.
It is important to remember that both the context and the map will
be valid for the lifetime of the hardware renderer (if the system
process goes down, all apps get killed as well.)
Every time the hardware renderer needs to render a bitmap, it first
checks whether the bitmap can be found in the assets atlas. When
the bitmap is part of the atlas, texture coordinates are remapped
appropriately before rendering.

Make gradients beautiful again
Bug #7239634
This change passes two matrices to the vertex shader instead of one.
We used to compute the final MVP matrix on the CPU to minimize the
number of operations in the vertex shaders. Shader compilers are
however smart enough to perform this optimization for us. Since we
need the MV matrix to properly compute gradients dithering, this
change splits the MVP matrix into two. This has the advantage of
removing one matrix multiplication per drawing operation on the
CPU.
The SGX 540 shader compiler produces the same number of instructions
in both cases. There is no penalty hit with having two matrices
instead of one. We also send so few vertices per frame that it
does not matter very much.

Fix modulation and gamma correction issues
Modulation is normally enabled in a shader when drawing with an alpha
mask (A8 texture.) Modulation is used to do one of two things:
- Colorize the primitive (to draw text in red for instance)
- Apply extra translucency (50% translucent circle filled with a bitmap)
The current implementation has four issues:
1. Unnecessary work is performed by assigning the modulation color
to vec4 fragColor early in the shader
2. The modulation color's alpha is applied twice when the primitive
is drawn with an SkShader
3. The decision to modulate is wrong and triggers when any of the
RGB channels is < 1.0. Only the alpha channel needs to be taken
into account to make the decision
4. Gamma correction is not applied properly
This change addresses all four issues above.

Correctly support pre-multiplied alpha, optimizations, more stuff.
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.

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.)

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.
