window: Be smarter about computing the default size

Browse Source 
See the code comments for the reasoning behind this. After we don't
force a "guessed" minimum size for labels anymore, a lot of issues
started to surface that this patch attempts to fix. In particular:

1) Tooltips where wrapped as much as possible.
2) The recentchooser submenu displayed only ellipsize dots.

/* (Note: Replace "size" with "width" or "height". Also, the request
* mode is honoured.)
* For selecting the default window size, the following conditions
* should hold (in order of importance):
* - the size is not below the minimum size
* Windows cannot be resized below their minimum size, so we must
* ensure we don't do that either.
* - the size is not above the natural size
* It seems weird to allocate more than this in an initial guess.
* - the size does not exceed that of a maximized window
* We want to see the whole window after all.
* (Note that this may not be possible to achieve due to imperfect
* information from the windowing system.)

/* We use these for now to not make windows too big by accident. Note
* that we still clamp these numbers by screen size. Also note that
* minimum size still overrides this. So keep your windows small! :)
