[PATCH] fbcon: Console Rotation - Add support to rotate font bitmap
Add support to rotate the font bitmap. To save on processing time, the entire
fontdata will be rotated on a console switch, then stored in a buffer private
to fbcon. To further save on processing, the fontdata will only be rotated if
the font has changed or if the angle of rotation has changed. Only a single
copy of the rotated fontdata will be kept.
