Detailed Description
A LaxFont using cairo.
Fonts in cairo have a base font (cairo_font_face_t) and a font at a particular size or transform (cairo_scaled_font_t), held here by font and scaledfont respectively.

Return the character width of ch.
This assumes the charwidth array exists already. If the real character width is 0, and r==0, this returns width of "\9f" or some such. Of course, this function is for latin-1 only.
- Todo:
- *** this is broken
Implements Laxkit::LaxFont.

Some languages change the character based on where letter is in word.
- Todo:
- This function as it stands is totally worthless and meaningless.
