[Upstream] [hardy] Usability Issue: Seperate PDF Export Settings

OpenOffice.org remembers settings made to the 'Export as PDF' dialog, for options such as:

General
- Image Quality (Lossless PNG or Lossy JPG)
- DPI Reduction

Initial View
- Panes
- Magnification
- Page Layout

User Interface
- Windows Options
- User Interface Options

But these options are remember without differentiating between Writer and Impress (and the other apps). This is significant because it's very likely that those settings would be different, for example:

Writer:
- Bookmarks and Page
- Fit width
- Continuos Facing

Impress:
- Page only
- Fit in Windows
- Single page
- Open in Fullscreen mode

As you can see, these settings are very different, and opening a Writer document in fullscreen mode is silly. So the settings should be remember on a per application basis (so a seperate memory for writer, impress, calc, etc).
