To use a font with wterm, the following must be true:

- the Width value in the _FontMetricStruct structure must be the SAME
  for all fonts.
- The Extent.x in the _FontStruct structure MUST be the same or less
  than the Width argument in the _FontMetricStruct structure.
- _FontStruct.Size.x can be 0.
- _FontStruct.Size.y can be 0.
- _FontStruct.BPChar can be 0.

To set a font in wterm, use the following escape sequence:

  ESC "f[tips]/[face]"

Where [tips] is the point size * V_TPP
Where [face] is the font name (e.g. cour)
Currently only NORMAL fonts will be read.

e.g. from a wterm shell, if I want to load the font /windows/fonts/cour.B14N
I could execute:

echo 'ESC"f154/cour"'

To generate the escape sequence from the shell, type CTRL-6 and then hit the
ESC key. (or put it in a prog or whatever)
