Added texture scaling functionality to drawquad
Added float3 to PBO function. For use with VMap or NMap or RGBMap.
Fixed several indexing and scaling bugs in VMap rendering debug code.
Changed to subsampling rather than interpolated downsampling. Faster and interpolation not needed.
Tried implementing single kernel. Because of divergent execution pattern it had no performance benefit.
Implemented basic normal and rgbmap debug modes.
