+How should we handle this? All rendering goes through the GraphicView (QG_GraphicView to be
+precise, soon to be merged in) as it should. So shouldn't we control the snapper through
+that class as well? Unfortunately, all actions derive from this class...
+
+Should they?
+
+Not 100% sure. It does seem to make more sense to have them be a part of the GraphicView,
+since snapping is a function of the grid and the entities contained in the view. (This would
+also hold for the preview as well.)
+
+On to the interface:
+
+For allowing the crosshairs to be drawn, we'd have
+void ShowSnapper(void)
+
+and
+void HideSnapper(void)
+
+to hide it. Maybe
+void SetSnapperCoords(Vector, Vector)
+
+for setting the coordinates?
