fd1fb639a1 Bring back support for glReadPixels screenshot path
Squashed commit of the following:

    sf: Always use opengles for screen capture

    Go back to the usage of GRALLOC_USAGE_HW_TEXTURE and GRALLOC_USAGE_HW_RENDERER
    in captureScreenImplLocked regardless of useReadPixels value

    This fixes the EGL_NO_IMAGE_KHR error returned from
    eglCreateImageKHR (blank images returned from screenshot path)

f008799d37 SF: Skip render-to-texture for color transforms
In cases where SurfaceFlinger is applying a color matrix (usually for
accessibility features), we previously would perform a render-to-
texture for the initial composition, and then apply the matrix during
a copy to the framebuffer. This changes that behavior to just apply the
matrix during composition without a render-to-texture pass.

This may result in a perceived change of the image in cases with alpha
blending, since the blending is performed at a different stage of the
pipeline and the system effectively performs non-linear blends.
However, neither this nor the prior render-to-texture pass is strictly
correct in that regard, and this approach is less error-prone and
likely faster.

c3ebe66b49 Add rotation to surfaceflingers screen cap.
+ This is needed so that activity manager does not
  have to do cpu side rotations when capturing recents
  thumbnails.

c18790018b SurfaceFlinger: Add sourceCrop to screenshot
Adds a sourceCrop Rect parameter to screenshot commands, which allows
clients to capture only a portion of the screen instead of the whole
screen.

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.

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.

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 (!)

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.
