Changeset 31 for trunk/tests/MainPterTest.cxx

Message:

The presenter is now able to control the Zoom: In, Out, toFit and toWidth.
The ZoomIn? and ZoomOut? controls also get sensitived depending if we can zoom in/out or not.

This puts an end to the presenter. I still need to check why compiling MainPterTest?.cxx takes this insane amount of time.
