* gradient, colours: use 24-bit colour depth internally on Wayland our Colour type assumes this anyway; lower colour depth should be handled by display backends * core: restore gradient color computation this was mistakenly disabled when moving to a unified Colour representation * core, gradient: use Colour type * tests: gradient: always test hsv/hcl colour computations no longer depend on the display backends we compile with, so these can be tested unconditionally now * gradients, specials: use Color type this makes specials now accept color names as well as hex codes, and removes all notions of color depth from gradient calculations --------- Co-authored-by: bi4k8 <bi4k8@github>
