  - find all allocations and check if context.temp_allocator could be used instead
  - bindless textures ones i have vulkan renderer

buggs

booted up blank screen and infinite loop or some on laptop [23.12.24|00:50]
after sleep deprivation
- laptop no longer 160-220 fps now 15-30 fps, PS: dafuck did i do ???
  - added text_draw_string() which is unbatched
  - add batched text draw call proc
- screen output buffer wrong size on startup -> prob. gl.Viewport()
