If the filter graph in an app closes out, the SurfaceTextureTarget
filter was losing the reference to the original surfacetexture, and the
app would re-start the graph without setting the surfacetexture again,
thus leading to a crash in registering a surface from surfacetexture.
Typical scenarios is start/stop immediately in camera effects recording.

1. In shade code of Vignette and Fisheye, change from
pixel coordinates to texture coordinates to avoid overflow.
2. Fix bug in ColorTemperature shader code
3. Revise shader code pseudo random number generator (used by
BlackWhite, Grain, Lomo, Documentary filters) to ensure
it produces no artifacts among devices with different precisions.

The aspect ratio sent from the camera app to the SurfaceTextureTarget
filter does not really matter now since the camera app handles
the re-sizing. Hence, the SurfaceTextureTarget filter needs to be render
in "stretch" mode all the time even though the aspect ratio sent to the
filter might indicate otherwise. The filter still needs the correct
frame size for things other than determining aspect ratio.

Related to b/5873421.
When an app using the SurfaceTextureTarget filter and the activity goes
out of focus such as onPause(), the underlying surfacetexture might not
be available anymore to the filter. The filter needs to be told about
that so that it does try to render into the surface corresponding to the
surfacetexture. For example, in Camera app, the VideoCamera activity has
to let the underlying effects graph know about the disconnect in the
onPause() method.

The SurfaceTextureTarget Filter was not unregistering the surface
on closing leading to crashes and blank screens.

This is part of the multi-project commit to move the filter-framework
from system/media/mca to frameworks/base/media/mca.
Note that the filter-framework will soon be replaced with a refactored
version currently under API review (also to go under frameworks/base).
This move is done now to unblock the PDK efforts.
