wmaker: add miniwindow apercu

Browse Source 
This patch is adding miniwindow apercu when the mouse
is over the miniwindows.

To enable it you have to run WPref, in Miscellaneous Ergonomic
Preferences, check miniwindow apercus.
Then, you will be able to see a screenshot of the app when the mouse
is over the miniwindow.
