[ros-diffs] [tkreuzer] 38633: - Fix creation of XLATE in IntEngCreateSrcMonoXlate. It was doing it wrong (colors swapped) and it only worked, because the caller of the function also passed the wrong arguments. - Mono DIBs need a special handling when creating the XLATEOBJ. Handle this in IntCreateXlateForBlt. Fixes broken colors on google/Firefox page.

Log:
- Fix creation of XLATE in IntEngCreateSrcMonoXlate. It was doing it wrong (colors
swapped) and it only worked, because the caller of the function also passed the wrong
arguments.
- Mono DIBs need a special handling when creating the XLATEOBJ. Handle this in
IntCreateXlateForBlt. Fixes broken colors on google/Firefox page.
