Tiled export format that is usable in Game Boy Advance projects.
Tiled should export based on a desired target GBA mode and desired number of layers.
To support the desired mode & layers, Tiled layers must be merged.
- How do we let the user control this merging?
Colour quantisation and palette allocation.
- How can we let the user decide how many palette entries should be used?
Semi-transparency should almost certainly be merged into lower layers.
GBA blending probably possible, but an entire layer must be marked as blending.
Alpha cutout certainly required.
Dynamic tile and palette manager.
Analytical per-layer?
Perhaps a dynamic tile blitter on the GBA could be used to avoid nearly-duplicate tiles.
Compression should be quite possible.
Tiled off-grid elements?
Likely able to be set-up in Tiled as "scroll speed". Parallax scrolling? Maybe possible with a per-line scroll speed option?
