[vulkan] Add support for building and loading shaders Shaders can be built as spv files and installed into $libdir/quakeforge/shaders or as spvc files and compiled into the engine. Loading supports $builtin/name to access builtin shaders, $shader/path to access external standard shaders and quake filesystem access for all other paths.

[vulkan] Add support for 9-slice rendering There's no API yet as I need to look into the handling of qpic_t before I can get any of this into the other renderers (or even vulkan, for that matter). However, the current design for slice rendering is based on glyphs (ie, using instances and vertex pulling), with 3 strips of 3 quads, 16 verts, and 26 indices (2 reset). Hacky testing seems to work, but real tests need the API.

#include "libs/video/renderer/vulkan/shader/slice.vert.spvc"
[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.

[vulkan] Add support for IQM models Despite the base IQM specification not supporting blend-shapes, I think IQM will become the basis for QF's generic model representation (at least for the more advanced renderers). After my experience with .mu models (KSP) and unity mesh objects (both normal and skinned), and reviewing the IQM spec, it looks like with the addition of support for blend-shapes, IQM is actually pretty good. This is just the preliminary work to get standard IQM models loading in vulkan (seems to work, along with unloading), and they very basics into the renderer (most likely not working: not tested yet). The rest of the renderer seems to be unaffected, though, which is good.

[vulkan] Switch to full screen triangle instead of quad While I have trouble imagining it making that much performance difference going from 4 verts to 3 for a whopping 2 polygons, or even from 2 triangles to 1 for each poly, using only indices for the vertices does remove a lot of code, and better yet, some memory and buffer allocations... always a good thing. That said, I guess freeing up a GPU thread for something else could make a difference.

[vulkan] Switch to full screen triangle instead of quad While I have trouble imagining it making that much performance difference going from 4 verts to 3 for a whopping 2 polygons, or even from 2 triangles to 1 for each poly, using only indices for the vertices does remove a lot of code, and better yet, some memory and buffer allocations... always a good thing. That said, I guess freeing up a GPU thread for something else could make a difference.

[vulkan] Create a water warp output pipeline Although it works as intended (tested via hacking), it's not hooked up as the current frame buffer handling in r_screen is not readily compatible with how vulkan output is handled. This will need some thought to get working.

Loading supports $builtin/name to access builtin shaders, $shader/path to access external standard shaders and quake filesystem access for all other paths.
