android_development/tools/emulator/opengl/tests/ut_renderer/RenderingThread.cpp
Stas Gurtovoy d32c2d9633 emulator opengl: system GLESv1 first commit. 
This is the first commit for the GLESv1 implementation.
It also includes needed fixes in emugen to support const types.
Also, changed glFinish definition in gl.in to match the
definition as in gl.h.
