Bug 50372: Setting stipple to NULL = X error

[Jamie Strachan <frostfreek yahoo com>]

I have posted a patch under bug 50372, that simply
ignores NULL stipples when setting the XGC.
(Also did the same for tiles.)

This means the XGC will have the previous stipple
defined until such time as another non-NULL stipple is
specified, or the XGC is destroyed.

While this is probably the easiest way to solve the
problem of eliminating the X Error, it occurs to me
that this may not be what is desired.

The API document does not specify what happens when
you specify the fill style as GDK_[OPAQUE_]STIPPLED,
and specify a stipple of NULL.
I would probably file that under "UNDEFINED
BEHAVIOUR", which can very well mean this patch is
sufficient.
