Transparency? I hardly knew 'er!

See merge request !264

Change the order of operations when applying transparency and colormap such that colormap isn't applied to the screen pixel twice (or, in the case of R_DrawTranslatedTranslucentColumn_8, thrice).

Please note I haven't touched the ASM equivalent, given as it's not actually used.
