We Need A Standard Layered Image Format

This is an interesting idea, though I cringe a little at using a relational database as a key/value store (as in the case of layer_attributes).

I wonder whether it would be more useful to just represent the whole thing as a big JSON structure with base64 blobs. Each layer can be an object in the "layers" array with the attributes as keys.

Layered images can easily grow to gigabytes in size. You do not want to store that much information in a format like JSON that must be opened into memory, parsed and stored in native objects. SQLite is RAM efficient and quick to open, even at large file sizes.

Fair enough - I rarely work much with images, so didn't even think of size.
