hack around layout qualifiers

The next shader compilation problem is that they are applying layout qualifiers
to function params. e.g

void WriteTextureCacheFeedback(
    vec2 lCacheCoords,
    ivec2 lResolution,
    float lfDesiredMip,
    layout( r32i ) iimage2D lFeedbackMap,      < --------
    uint liFeedbackIndex )

layout( r32i ) can only be applied to uniforms.

I've attached another hack that together with the other hack makes the game
playable for me.
