; ---- the frame's autorelease pool --------------------------------------------------------------
; MoltenVK and CAMetalLayer autorelease objects on every frame (the drawable, each render pass's
; descriptor), and a program that pumps its own events never drains a pool: without this they are
; kept for the life of the process - 160 MB/s of small allocations in a windowed valley.
; lvk_frame_pool() pops the pool the last frame pushed and pushes the next one.
