NO. You should only use the WIMP calls to set the palette when running
on the desktop, I think... I don't think the WIMP traps VDU 19's...

If you use Wimp colour-setting calls, this shouldn't be a problem.

If not:
  * If you call ColourTrans_InvalidateCache any subsequent redraws should
    do their best to get the colour right given the new palette.
  * Issue your own redraw broadcast
