The format already requires ARB_HALF_FLOAT_PIXEL, which is supported
by GF FX. The format also requires ARB_TEXTURE_FLOAT to work properly,
which as far as I can see from the list at Delphi3D isn't supported by
GF FX. The next patch adds this extension check. Wrt
ARB_COLOR_BUFFER_FLOAT, I'm not sure how it would imply post ps
blending support?
