Bzzzt, wrong, but thanks for playing.  Outside of Looking Glass and related 
projects, Composite maps pictures untransformed, and using Render not GL.  GL 
engines in general do not special case this path because untransformed 
application of textures to the framebuffer is not the typical use case for 
GL.

And mapping those pictures transformed is sufficiently expensive that you 
really don't want to do it in software.
