can we just move this to GLImage instead but keep it a function only for
testing?

[dshwang, 2016/01/11 15:31:10]

Currently CL merge this and TextureFormat() in gl_image_memory.cc into
GetTextureFormatFrom() in gl_utils.h

GetTextureFormatFrom() can be located in gl_image.h. Do you want to move it to
gl_image.h?
