Do you really want to let clients control shadow color, dimensions & offsets?
Shadows resemble a light model, but with such setup they'd probably end up
like psychodelic ;-)
("I - that is /ME/ - is the most important client on the block and I - that is
*ME* - want the biggest and most colorful shadow!" :-)
Even if not, it would end up like Gtk+ an Qt look different - again :-(
What we do need are reliable hints on whether the window
- does not want a shadow at all ("OSD" type)
- can use "normal" (rectangular) shadows despite using an ARGB color table or
(slightly) shaped. If not it should be not a big deal to copy the alpha part
of the window texture and blur (and cache) it to form a shadow.
Cheers
