+ * Quicktime movies and PICT castmembers continually display

+ * this XObject can be used to patch this problem
+ * use mPatchIt message on the same frame as the palette switch
+ * pass in the stage window coordinates when creating the XObject

+ * From: http://www.zeusprod.com/technote/patchpal.html
+ * The FixPalette XObject is needed when using QuickTime movies with
+ * more than one custom palette. If it not used on the PC, nor is it
+ * needed if you are only using one custom palette. If the first
+ * QuickTime you play looks fine, but the second QuickTime video
+ * that is played looks funky or psychedelic, then there is a good
+ * chance that the FixPaletet XObject will solve your problem.

+ * It's only necessary on Mac.
