 ### Snap to grid when moving an object
 
 1. Currently snapping to the grid snaps the mouse cursor to the grid, however, that can lead to object still not lining up properly. The object's bounding box should be what snaps to the grid. If a reference point is needed for snapping, use the object's upper left point of the bounding box.

+### Seletion bounding box as well as rotation 'dot' should stay in front of all other objects.
+If an object is selected, it's bounding box and rotation dot should be in front of all other objects.

+### Touchpad panning is too slow
+Panning using the touchpad does not moves too slowly.  We need to increase the distance the panning moves through touchpad.
+
+### Zooming in/out
+When zooming in, we should use the mouse cursor as the zoom in point.  If the cursor is in the window should determine where the zoom should happen.
