Mathias Agopian ff2ed70fa3 color blindness enhancement
This is an attempt at improving the experience of
users with color vision impairement.

At this time this feature can only be enabled for
debugging:

  adb shell service call SurfaceFlinger 1014 i32 PARAM

  with PARAM:
   0 : disabled
   1 : protanomaly/protanopia simulation
   2 : deuteranomaly/deuteranopia simulation
   3 : tritanopia/tritanomaly simulation
  11, 12, 13: same as above w/ attempted correction/enhancement

The enhancement algorithm tries to spread the "error"
such that tones that would otherwise appear similar can be
distinguished.

Mathias Agopian 49457ac092 Encapsulate textures into their own Texture class
the main reason for doing this is so that we can have
access to informations about a texture (like its dimension)
close to where we generate and use shaders in ES 2.0.
Previously, there wasn't any way to get to a texture's size
from a RenderEngine implementation.

Mathias Agopian 458197de00 Fix ES2 composition on some devices
- turns out fragment shaders don't have default precision by default
- GLES 1.x extensions that became core in GLES 2.0 don't always work
  as extensions in GLES 2.0 (!)

Mathias Agopian 875d8e1323 Refactor SF. Move all GL operations in their own class.
this is the first step to add support for GLES 2.x, this
change breaks the dependency of SF on GLES 1.x by moving
all operation into their own class.
