 # 2023-10-24 E318
 - [ ] use new hashmap for textures
-    - [ ] use vk_texure array directly as open addressing hash table
-        - [ ] Completely hide `struct vk_texture`
-        - [ ] just try
-        - [ ] texture indexes are no longer consecutive
-        - [ ] blue noise texture breaks => make it a separate (3d) thing
-        - [ ] index=0 is now valid
-            - I. mark 0 as occupied to avoid allocating it
-            - II. Increase all returned indexes by 1. Then dec it back wherever it is passed back
-        - (SAD): cannot make builtin textures have stable indexes anymore
