when you create a pixmap from XPM data (or an XPM file) you get two
data structures, the pixmap and a bitmap (1 bit pixmap). the bitmap is
the "mask". so, to create a custom scrollbar, get the XPM data (or
some other image format that can be used to create a pixmap), create
the pixmap for the floater (the "knob") and the background, then pass
in both pixmaps and bitmaps.

clear?

ps. this comes from gdam. you may want to check on their GTK+2 port,
    if any.
