  25 /* Georg explanation of current situation:
  26 AFAIK the text painter was used to export math formulas as ASCII art.
  27 The text painter is     like a real painter, but operating on a very coarse
  28 grid of character cells where each cell can be filled with an ASCII character.
  29 I don't know why it is currently disabled. I do know that we have a bugzilla
  30 request for reenabling it.
