Wrong number of arguments to XCreatePixmapFromBitmapData.  If your width or
height are 0 that would produce the BadValue error.  But it is probably the
depth argument, which is missing, which is resulting in the BadValue error.

The glossary defines drawable.  The server uses the drawable argument to 
determine on which screen to create the pixmap; pixmaps can only be used
on the screen on which they were created.
