replicant-frameworks_native/opengl/tests/gl2_copyTexImage/gl2_copyTexImage.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.
