It must set it to 0 if the alpha is 0 to avoid problems with special colormap detection. - Changed SPECIALCOLORMAP_MASK again so that it does not interfere with any valid setting. It must use a value with a 0-alpha because these are guaranteed not to be produced by the DECORATE code elsewhere. - Fixed precision issues with AddFixedColormap's search for identical colormaps. - Added custom colormap support to texture composition code. - Fixed initialization of FSpecialColormap::GrayscaleToColor. This is not a mapping from the palette but from a [0,255] grayscale ramp and used to apply colormaps to true color images for texture composition. SVN r1867 (trunk)
