2.5

Text drawing in 3D window fixed, using BLF default font (yes, nice AA'ed
fonts too :)

Solved it by gathering all strings that needs to be drawn for an object,
and then draw in end of object drawing, in pixelspace. Also cleaned up
some of the code for projecting 3d coords, much nicer now (mat stored in
region-view3d)
