820 LordHavoc: here's the readable version of the interpolation
821 code, not quite as easy for the compiler to optimize...
823 dsfrac is the X position in the lightmap pixel, * 16
824 dtfrac is the Y position in the lightmap pixel, * 16
825 r00 is top left corner, r01 is top right corner
826 r10 is bottom left corner, r11 is bottom right corner
827 g and b are the same layout.
828 r0 and r1 are the top and bottom intermediate results
830 first we interpolate the top two points, to get the top
833 r0 = (((r01-r00) * dsfrac) >> 4) + r00;
834 g0 = (((g01-g00) * dsfrac) >> 4) + g00;
835 b0 = (((b01-b00) * dsfrac) >> 4) + b00;
837 then we interpolate the bottom two points, to get the
840 r1 = (((r11-r10) * dsfrac) >> 4) + r10;
841 g1 = (((g11-g10) * dsfrac) >> 4) + g10;
842 b1 = (((b11-b10) * dsfrac) >> 4) + b10;
844 then we interpolate the top and bottom samples to get the
845 middle sample (the one which was requested)
847 r = (((r1-r0) * dtfrac) >> 4) + r0;
848 g = (((g1-g0) * dtfrac) >> 4) + g0;
