/*

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.

compute at which row the glyph starts to be in it,

compute which is the first glyph inside the left

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

all glyphs are the same height and don't overlap.
