'Scale of layer' feature

Suggestion
#1

Would love to see ability to set a variable scale to layer, mainly for parallax workflow.

Background layers are further away and are smaller with a perspective camera. To offset that I scale up background layers in my engine, but that means they’re harder to work on in Tiles: they’re no longer align with foreground layers.

For preview purposes i’d love to have scale option (like Tiled already has Opacity).

Tiled is getting a parallax preview feature in 1.5 (you can already test this feature in the snapshot builds), so you should hopefully not need to do any scaling anymore. Tiled’s parallax feature doesn’t scale the layers themselves, instead each layer gets scrolling factors (horizontal and vertical) you can set, which is a more common way to do parallax, and can hopefully be adapted to your engine.
