replicant-frameworks_native/opengl/tests/hwc/hwcTestLib.cpp
Andy McFadden 6ef57d7b36 Restore old OpenGL tests 
These tests call android_createDisplaySurface() to get a
FramebufferNativeWindow that is passed to EGL.  This relies on the
existence of the framebuffer HAL, which is not supported on many
recent devices.

This change adds a new "window surface" object that the tests
can use to get a window from SurfaceFlinger instead.  All tests
except for the HWC tests now appear to do things.

The HWC tests don't do anything useful, but they no longer depend
on the android_createDisplaySurface() function.

* a table that provides the full and in gamut ranges of each of the
* supported graphic formats. The full range is given by members named
* c[123]Min to c[123]Max, while the in gamut range is given by members
* named c[123]Low to c[123]High. In most cases the full and in gamut
* ranges are equivalent. This occurs when the c[123]Min == c[123]Low and
* c[123]High == c[123]Max.
*
* The input and produced colors are both specified as a fractional amount
* of the full range. The diagram below provides an overview of the
* conversion process. The main steps are:
*
* 1. Produce black if the input color is out of gamut.
*
* 2. Convert the in gamut color into the fraction of the fromFromat
* in gamut range.
*
* 3. Convert from the fraction of the in gamut from format range to
* the fraction of the in gamut to format range. Produce black
* if an equivalent color does not exists.
*
* 4. Covert from the fraction of the in gamut to format to the
* fraction of the full range to format.
