[uzkddxwx] Sideways font

Create a font with every character rotated 90 degrees counterclockwise.  Then rotate the display (xrandr) 90 degrees clockwise so the letters read downwards.  Hopefully this isn't too difficult to read, as we are used to vertical text on signs.  Reading top to bottom then right to left happens to be identical to classic Chinese and Japanese writing.  The goal is to make good use of space on landscape displays, say for code or a document.  Need to recalibrate the mouse.

The other way is lots of columns.  Both of these methods are old, seen in physical scrolls held in landscape.
