Gem operations have to happen in a definite time frame, because all OpenGL 
operations are going through a single pipe to the renderer. However, I'm 
pretty sure that we're currently using 3 definitions of the word "pipe" at 
once. By "multiple pipes" do you mean multiple connections from outlet to 
inlet ?

Even if [pipe] allowed a gemstate to go through it, it doesn't mean it 
would do what you want it to do. for GL operations, the meaning of an 
operation is completely dependent on its order, and if it's not scheduled 
by [gemwin] itself, chances that it'll fall in the cracks between the 
frames and die.

This does not apply to [pix...] objects, except the ones that are both pix 
and GL ([pix_texture] [pix_snap] [pix_snap2tex]).
