True for XCreateFontCursor(), but XCreateGlyphCursor() shouldn't be
getting "themed" either. XCreateGlyphCursor() takes source_font and
mask_font parameters; those should be used, not ignored.

With XCreateFontCursor(), the "font" is specified as being
system-dependent, so it isn't an issue in that case. Even so, I would
rather just see applications use XcursorShapeLoadCursor(), rather than
expecting Xlib to do it for them.
