[vulkan] Create the non-C side of the sprite pipeline This adds the shaders and the pipeline specs. I'm not sure that the deferred rendering side of the render pass is appropriate, but I thought I'd give it a go, since quake sprites are really cutoff rather than translucent. 2021-12-14 05:44:16 +00:00			`#version 450`

[vulkan] Implement the sprite render passes It turned out the bindless approach wouldn't work too well for my design of the sprite objects, but I don't think that's a big issue at this stage (and it seems bindless is causing problems for brush/alias rendering via renderdoc and on my versa pro). However, I have figured out how to make effective use of descriptor sets (finally :P). The actual normal still needs checking, but the sprites are currently unlit so not an issue at this stage. 2021-12-14 16:22:05 +00:00			`layout (set = 1, binding = 1) uniform sampler2DArray Texture;`
