Accept windows' depth, visual and colormap instead of always using those of the root window. Internal windows such as menus behave as before. In conjunction with a compositing manager on a display supporting the RENDER extension windows can now manage their own opacity. I wrote the patch after reading the FAQ for urxvt, which says, regarding transparency support: "3. Use an ARGB visual: urxvt -depth 32 -fg grey90 -bg rgba:0000/0000/4444/cccc This requires XFT support, and the support of your X-server. If that doesn't work for you, blame Xorg and Keith Packard. ARGB visuals aren't there yet, no matter what they claim. Rxvt-Unicode contains the necessary bugfixes and workarounds for Xft and Xlib to make it work, but that doesn't mean that your WM has the required kludges in place." In conjunction with a compositing manager (I tested compton) it does work and urxvt draws a semi-transparent background with fully opaque foreground text and scrollbars; much prettier than applying a blanket transparency value over the whole window with the compositing manager. Other application windows I tested were, as expected, drawn the same as before. I verified that urxvt is drawn in the same way when using xfwm4 (with builtin compositing). Since Window Maker doesn't (at time of writing) have its own compositing manager I should clarify that one is required to see any benefit from this patch. Whether or not this feature is useful for any application other than urxvt I don't know, though I assume that an application which chose an ARGB visual in the same way would be able to draw itself prettily. On a display without RENDER things work just as they do without the patch. I have, however, only been able to test on a fairly standard TrueColor display supporting multiple colour depths with 24bpp being the default. Testing with more ... exotic ... display types would probably be advisable.
