Re: Questions about WindowMaker's Alpha and Shadow

[Fred Kiefer]

Hi Austin,

what happens here is that we delegate this functionality to the window manager. 
That may either implement it or not. The standard for this interaction can be 
found here: https://specifications.freedesktop.org/wm-spec/wm-spec-1.3.html
If it does not work on your machine it might either be that you window manager 
does not adhere to this standard or that the interpretation differs from the 
one in GNUstep.

Hope this helps,
Fred
