Patrick Jaap 8d1dc9a662 emfio: unit test for the EMF+ renderer
Two unit tests, which test the EMF+ records DrawString and DrawLine
independently.
To this end, a fixed view decomposition of metafiles is implemented.

The chosen primitives should be optimal, even for future extensions
of the EMF+ parser.
