Commit0e8fbdbdremoved the rg_texture requirement from vo_opengl; commit541f6731changed to a more convenient method. Both commits broke vo_opengl_old in some ways. vo_opengl_old always requires GL_ALPHA for single-channel texture, because it draws the OSD without shaders and by using certain blend modes. So we need to explicitly distinguish between vo_opengl and vo_opengl_old in the OSD renderer, and force fixed texture formats for vo_opengl_old. The other logic is specific to the internals of vo_opengl. (Although it might be possible to get the same result by playing with the old GL fixed-function functions in vo_opengl_old. But seems like a waste of time.) Fixes #1370.
