Description of problem:
GPDF does not seem to remember the zoom level you were last using - at
least not for the Best Fit button. I would expect it to stay in Best
Fit mode until I turn that off, even if I close and reopen the viewer,
i.e. to persist the current zoom level as an invisible preferences
setting for the app in GConf.

Note that GGV, which serves a very similar function to GPDF, has a
different UI. It has controls to change the current zoom level and fit
mode, but it also has a GGV Preferences dialog which has a Document
tab with settings like Default Zoom and Auto-fit mode, which you can
use to control the default state of these controls at startup. I
personally consider this is a bit more than is needed; would be enough
for most people (IMHO) to simply keep the last settings.

At any rate, GPDF and GGV should be made consistent in this respect.

Maybe we should just do this in evince.
