so is it this what you had in mind? (using the texture-info of 
[gemframebuffer] and a [pix_texture] to setup the texcoords correctly)

non-rectangle, or 2d :-)

the "rectangle" message is really just an other name for the 
"mode"-message, you use it identical:
[rectangle 1( - turn on rectangle texturing (of supported)
[rectangle 0( - turn off rectangle texturing.
