- this works for fonts with glyphs <= PPW bits wide.
-
- 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.
