early draft

<greg> add a slider like in oo.org

<ale> here the zoom functions i (would) need:

an easy way to get back at 100% (eventually see the current %... which could be an input box)
eventually a way to switch among two zoom levels (mostly all page on screen / detailed view)
ctrl+mouse wheel to zoom in and out
+ / - in non edit mode and ctrl++ / ctrl+- in edit mode to zoom in and out
a zoom tool to make a "selected area" fill the window
eventually some keys like in inkscape (1, 2, 3, 4, 5) to fit to screen with different criteria
for the beginners it should be possible to zoom in and out with the zoom tool
