Detailed Description

Everything ez_scene_init needs: storage and framebuffer geometry.

Every pointer is borrowed and must outlive the scene. The cache arrays are the six ra8_tile_cache_cfg_t needs; the three scratch buffers are the composite's. The framebuffer is carried here (as well as being bound into ra8_gfx) because the scene hashes it for the golden, and ra8_gfx exposes no accessor for the binding.

Invariant

Every pointer is non-NULL and every capacity matches its enum.

Example:

const ez_scene_cfg_t cfg = { .fb_w = 1024, .fb_h = 600, .cell_mem = s_cells, ... };
