[ANGLE Snapshot] GLES2 translator on top of ANGLE
This patch modifies our GLES2 translator to allow it to mount on top of
ANGLE. Because ANGLE is a GLES2 backend while previously our translator
assumes desktop GL backend, some modifications are required.
The main changes in this patch include:
(1) Pass a flag to GLES translator to tell if it is running on top of
another GLES backend
(2) Desktop GL sometimes assume EXT postfix for some functions while
GLES does not. Modify dispatcher so that it loads func as well funcEXT
and funcOES as alias.
(3) ANGLE does not like GL_RGB8 and GL_RGBA8 texture internal formats.
Change them to GL_RGB and GL_RGBA.
(4) Bypass some texture parameter validations when using ANGLE backend.
(5) Ignore the parsed shader and use orignal shader source when using
ANGLE backend.
