[vulkan] Implement order implement transparency It's a bit flaky for particles, especially at higher frame rates, but that's due to supporting only 64 overlapping pixels. A reasonable solution is probably switching to a priority heap for the "sort" and upping the limit. 2022-11-30 18:00:47 +00:00			`#include "oit.h"`

[vulkan] Add partial support for cube maps to OIT Partial because frame buffer creation isn't handled yet (using six layers), but using layer a layer capable view and shaders doesn't cause problems (other than maybe slightly slower code). 2023-01-24 01:09:00 +00:00			`ivec3 coord = ivec3(gl_FragCoord.xy, gl_ViewIndex);`
