It's easy to forget to tick the snap to grid box and just assume you are going to get snapped to a grid, then export a map with nonsense size and have to start the export over.

Also, when snapping to grid and resizing, if snap to grid enabled, allow an option to only snap to WHOLE grid points, not half-grid and make that the default.

Currently, too many ways to mess up grid-aligned resize. It shouldn't be so easy to make a mistake.
