Steps to reproduce
1.	Open a new presentation
2.	Set zoom value to “Fit width” (View -->Zoom --> “Fit width” --> “OK”)
3.	Resize application’s window

Actual result: Size of the slide remained the same, i.e. if you have decreased
window’s width, slide’s width no longer fit the window. If you have increased
window’s width, slide now takes up only a small part of the window.

Expected result: Slide’s size changes to fit new window’s width. It’s the kind
of behavior I would expect from the name "Fit width". Besides “Fit width and
height” zoom is preserved while resizing window.

Notes
1.	The same for “Optimal zoom”
2.	The exact ways we change zoom (menu, task bar button, status bar slider) and
resize the window do not matter.
3.	The same issue in OOo3.3
