[vulkan] Implement font rendering It is currently an ugly hack for dealing with the separate quad queue, and the pipeline handling code needs a lot of cleanup, but it works quite well, though I do plan on moving to HarfBuzz for text shaping. One nice development is I got updating of descriptor sets working (just need to ensure the set is no longer in use by the command queue, which the multiple frames in flight makes easy). 2022-09-02 05:23:19 +00:00			`#version 450`

[vullkan] Rework Draw implementation Line rendering now has its own pipeline (removing the texture issue). Glyph rendering (for fonts) has been reworked to use instanced quad rendering, with the geometry (position and texture coords) in a static buffer (uniform texture buffer), and each instance has a glyph index, color, and 2d base position. Multiple fonts can be loaded, but aren't used yet: still just the one (work needs to be done on the queues to support multiple textures/fonts). Quads haven't changed much, but buffer creation and destruction has been cleaned up to use the resource functions. 2022-10-03 01:29:49 +00:00			`layout (set = 1, binding = 1) uniform sampler2D Texture;`
