- this works for fonts with glyphs <= 32 bits wide, on an
- arbitrarily deep display. Use cfbTEGlyphBlt8 for 8 bit displays.
-
- This should be called only with a terminal-emulator font;
-this means that the FIXED_METRICS flag is set, and that
-glyphbounds == charbounds.
-
- in theory, this goes faster; even if it doesn't, it reduces the
-flicker caused by writing a string over itself with image text (since
-the background gets repainted per character instead of per string.)
-this seems to be important for some converted X10 applications.
-
- Image text looks at the bits in the glyph and the fg and bg in the
-GC. it paints a rectangle, as defined in the protocol dcoument,
-and the paints the characters.

- compute at which row the glyph starts to be in it,
- and at which row the glyph ceases to be in it
- compute which is the first glyph inside the left
- edge, and the last one inside the right edge
- draw a fractional first glyph, using only
- the rows we know are in
- draw all the whole glyphs, using the appropriate rows
- draw any pieces of the last glyph, using the right rows
-
- this way, the code would take advantage of knowing that
