While prototyping I came across a sort of bug in the Texture module. Both the canvas2D and webGL implementations use ~~settings.tileSize.width and ~~settings.tileSize.height to account for different tile sizes as set in the editor.
However, the TILES_PER_LINE variable just below it is hardcoded to 16, which would be the case with the default 8x8 tiles. It was a simple fix to change the value to what I needed (8 tiles per line, 16x16 tiles), but it would be nice to have it automatically set as so in a future update.
Cheers!
