Not sure we need this change as part of this patch but it we do then I'd rather
see the TextureFormat function in GLImageMemory moved to the GLImage class.

[dshwang, 2016/01/13 17:07:42]

Done.
we need, because both GLImageMemory and unittests need it.

Unlik GLImageSharedMemoryTestDelegate and GLImageRefCountedMemoryTestDelegate,
GLImageOzoneNativePixmapTestDelegate cannot use
GLImageMemory::GetInternalFormatForTesting because GLImageOzoneNativePixmap
doesn't inherit GLImageMemory.
