Ehrm... after having had a brief [exchange](https://gitlab.freedesktop.org/mesa/mesa/-/issues/11359#note_2479687) with stefan I'd like to interject for a moment if you will.
I can see why "modern design" would want everything composited and nothing really in control of the hardware.. but I can still totally see use cases for the opposite too (on top of the fact I'm not sure how nutty reinventing yet another wheel may be for you)
Wayland itself (just like with tearing and fullscreen unredirect) is backtracking from its far too smoothed ideals, and both [color](https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/14) and [mode](https://gitlab.freedesktop.org/wayland/weston/-/issues/866) controls are actually on the table.
