clip fewer children

[lawson_whitney at juno.com]

Good day!

This is just a knee-jerk reaction to a null-pointer dereference, but it
makes my app run again.  If somebody figures out how to stop the pointer
being null in the first place, maybe that is a better way.  I'll send a
backtrace to wine-devel.

ChangeLog:
	* dlls/x11drv/winpos.c:
	Lawson Whitney <lawson_whitney at juno.com>
	Don't try to clip children that aren't there.

Or, if you prefer,

ChangeLog:
	* dlls/x11drv/winpos.c:
	Lawson Whitney <lawson_whitney at juno.com>
	Protect against null-pointer dereference.


Regards,

Lawson
