- Add generic full-page templates. (This feature from 3.4 was missing)
- Also add generic half-page, quarter-page, and envelope templates.
- Add several more common envelope sizes to page-sizes.xml
- Qt print backend does not need pwg_size.
- Replace with pwg_class, to distinguish between ISO and NA sizes
- Added side pane for product preview and information
- Product selection is done with a separate pushbutton, so that user gets a
chance to preview the complete product information before committing to the
selection
- Supports two view modes: Grid View and List View
- View mode is automatically stored in Settings, so it will default to the
user's prefered mode
- Should address most concerns in #109 and #142
