/*
|
|
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.

calling the non-terminal text is easy, but slow, given

what we know about the font.
|
|
|
|
the right thing to do is something like:
|
|
for each clip rectangle
|
|
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
|
|
all glyphs are the same height and don't overlap.
