Currently, snapping to a screen edge and then snapping to maximize
results in both the natural_geometry and tiled state of the view
getting messed up. After unmaximize, the view ends up in a weird
state (tiled location but natural/untiled size).
There are also a couple of sketchy things going on in the code:
- interactive_begin() pokes its own values into view->natural_geometry
to force view_maximize() to set a particular geometry.
- interactive_end() "fixes" view->natural_geometry after calling
view_maximize() to save the original geometry from the start of the
interactive move/resize.
To fix all this:
- Adjust/expand the API of view.c so that the interactive.c can
avoid this "back door" of overwriting view->natural_geometry
directly.
- Save the natural geometry and the tiled state of the view in
interactive_begin() when starting to move the view. When done,
interactive_end() will update the tiled state if appropriate but
*not* overwrite the natural geometry.
