-Should snap to the nearest "snap point" if within n pixels of it in screen 
space (NOT world space).  Maybe try n=5?

If token radius <n in screen space, then n=token radius.

Snap points in world space are <x + r/2, y + r/2>, where <x, y> is the 
coordinate of a grid intersection and r is the radius of the token being 
snapped.  With a standard token (r=1) this will snap to the grid square 
centroid.

Note that this allows a token to snap to a subgrid if it is a small size, and 
allows a larger-sized token to snap correctly such that it occupies multiple 
squares equally (i.e. a token of diameter 2 should snap to a grid point, not a 
centroid).
