At the moment, you select the tile, meaning the pattern you want to reproduce, and then, at the layout view, the default squared form can be resized with ease, filling its whole size with the chosen pattern.
Well, what I was thinking is that maybe we could select the type of form we want the pattern to fill in: squared, circled or free, choosing this way its bounds with edging dots, the same way we set the polygon shape of the sprites in the editor.
This way, developers would be able to create rich scenarios with flexibility, using tiled background's features to set their layouts with better performance and amazing visual variety.
As I already said, i don't know if this is possible at the moment, at any moment or anything.
But, any way, thanks!
