fdo#44010: fix vertical text frame borders:

Frames with text direction Vertical RTL have their borders mangled while
painting, everything is rotated 90 degrees and so the model "left" border
ends up being painted as top border etc.  Clearly the new drawing layer
based painting code is very surprised by this and ends up painting only
points instead of lines.
(regression from 0f0896c26fb260d1bbf31d7a886df3f61837f0f2)
