[Xquartz-dev] Line drawing in 1.5 and 1.6 servers

[Martin Otte]

Hi,

Attached is a simplified test case showing that in a call to  
XCreateSimpleWindow, the border around the subwindow is not displayed.  
With the 1.4 server, the program displays:

but with the 1.5 server, the border of the inner window is not shown:

I also added this example code to bug report #290.

Hope this helps,
Martin
