Yes, that's right.  The purpose of passing the raster is to synchronize
the raster colormap with what is needed in the pixmap.  Under X,
the Xpm library does closeness-matching and the raster isn't referenced.

I think you'll be ok if you do a setRaster: before running drawX:Y:.
Let me know if that's not the case.
