there is an evil trick you can play... that will - for the most part,
technically work (if your drivers don't "suck") these days. but i feel obliged
not to share that trick as every wm/compositor author on the planet will kill
me (hell i'd kill myself) for suggesting it.

in the end what you want requires either the wm+cm implements it - or it
supports it specifically. it's all about mechanism not policy in x11 and in x11
the wm+cm (wm in older days alone) define such policies.
