xournal should have an option to rotate image / text 90o

[Susan Cragin]

This is an enhancement request, not a bug.
Xournal is often used to annotate PDFs.
My computer has a touchpad and the best way to read PDFs is flipped to the side, with pen in hand.
I would like an option (FBreader and Adobe have it) to rotate the document 90o so I can annotate in that direction with my pen.
