I am using the XSetPlaneMask library call and drawing a string using
the XDrawImageString. The string given to XDrawImageString is drawn
in all planes, regardless of the value of the mask given to
XSetPlaneMask. That is, even if plane_mask is set to 0, the string is
displayed to all planes. Calls to other library routines such as
XDrawString work as expected.

The O'Reilly manual states that XDrawImageString (like XDrawString)
DOES pay attention to the plane_mask component of the GC.

I'm running on a SparcStation 1 with X11R4 from MIT. When I tried
this on a Sony Running X11R3, however, XSetPlaneMask does seem to work
correctly with XDrawImageString.

What gives?
