Maintenance release, not feature complete.
BUGFIX:Commit not working properly when there is a static sprite batcher in a prefab
FEATURE:Force resolution in Editor. Lets you force a display resolution - you can shrink the game window and still simulate placement on full resolution
BUGFIX:Fixed bug where sprite collection was being rebuilt a lot more often than it should
FEATURE:Shortcut to "edit sprite collection" directly from sprite
BUGFIX:Memory leak in textmesh & sprite with polygon collider when instantiating and destroying them in game.
Still TODO for 1.57:
Cache normals instead of calling Recalculate normals - will be much faster for materials with custom shaders
