Volker Ruppert 462871fd3a - Improvements for dimension_update() in text mode and text_update() 
- The emulated vga card issues a dimension_update() using the real
    screen dimensions and the real font height.

  - The gui selects a font with the requested height or it recalculates
    the screen height if the font height is not available.

  - The text_update() function uses a new variable 'ncols' instead of the
    fixed value of 80 for the number of text columns.

  I have tested the changes with X11/Linux, SDL, wxGTK and win32. The changes
  in the other guis are not tested yet.
