...neither:  this is a texture on the graphics card, so you can  
imagine it as tho it is an offscreen window that you never see unless  
you apply it to a primitive like any other texture...

...I tend toward control and manips:  I don't think we need a whole  
new folder, because we should be able to roll in backward's  
compatibility via c++ magic...

...this is pretty different from pix_buffer, and works at a whole  
other level...however, this "named buffer" stuff is applicable to the  
eventual bigger idea of the multiple_window branch, where you'd be  
able to associate multiple chains to either offscreen or onscreen  
windows (or both?)...but this is kind of a first step that enables  
lotsa cool stuff NOW ;-)

...multitexture was really part of a "trilogy" of related changes to  
bring GEM into the current "state of the art"...
