Pixel color components can be scaled using either bilinear interpolation or a multitap filter. The multitap filter provides better results, but can't be selected when the alpha layer need to be scaled down by more than 1/2. Disable alpha scaling when the input has a fixed alpha value, and program the UDS to output a fixed alpha value in that case. This ensures the multitap filter will be used whenever possible.
