dlls/x11drv/window.c

[Michael Cardenas]

Changelog:
This patch adds a check on the size of windows that are requested to be
created in X11DRV_CreateWindow. 

It fixes a crash in word when opening documents. 

It caps window sizes at 65535, since XCreateWindow uses unsigned ints
and the X protocol uses int16's. This prevents wine from trying to
create windows that cause the X server to error out, so it prevents a
crash in wine. 

it is a patch against the 04/23/2002 cvs.
