Spoike dbfd69f572 preliminary support for qc rendertargets with d3d11. I took some shortcuts so try not to combine it with other render target stuff just yet. 
flipped gl qc rendertargets to logically be top-down. the joys of weird matricies is a sight to behold.
try to fix threading dependency on recent versions of windows.
break some other related stuff.
