I have a number of applications now that work pretty well on my sun
and make use of XCopyPlane() to copy a simple 1 bit Pixmap to a window.

However, when I try to run them on a VS3100 running Xqdss (a 4 bit deep
display), they don't work.

It appears that the XCopyPlane() is a complete no-op.  It changes
neither the foreground nor the background pixels in the destination
window.  Oh, if instead of making my source Pixmaps 1bit, but instead
build them in in 4bit "color" and use XCopyArea(), it works fine.

Does anyone have a fix for this?  It's a real pain that X can't do
bitmaps.
