Bug 60656 - Emf image support in slideshows

- use Rectangle2D instead of Dimension2D for image bounds
- fix shearing transformation
- fix rendering of font attributes (bold/italic/...)
- emf+: needs its own object table and properties table
- emf+: add linear gradient handler
- emf+: handle brush data of pens
- wmf/emf/emf+: position right aligned text correctly
- emf+: use emf+ instead of emf records in dual-mode
- emf+: handle region data and operations correctly
- emf/+: map font weight to awt font weight correctly
