I still have to hook in a sys_gridsize and a g_editor field for it.

Btw-- ran into a weirdo bug testing this. Sometimes I can drag an object
outside the window bounds (as you should be able to do). Other times the
object stops at the edge of the window and cannot be dragged any further.
Same with or without snap-to-grid, so I'm not sure what the problem is
there.
