-/*
-	we should eventually special-case fixed-width fonts for ImageText.
-
-	this works for fonts with glyphs <= 32 bits wide.
-
-	the clipping calculations are done for worst-case fonts.
-we make no assumptions about the heights, widths, or bearings
-of the glyphs.  if we knew that the glyphs are all the same height,
-we could clip the tops and bottoms per clipping box, rather
-than per character per clipping box.  if we knew that the glyphs'
-left and right bearings were wlle-behaved, we could clip a single
-character at the start, output until the last unclipped
-character, and then clip the last one.  this is all straightforward
-to determine based on max-bounds and min-bounds from the font.
-	there is some inefficiency introduced in the per-character
-clipping to make what's going on clearer.
-
-	(it is possible, for example, for a font to be defined in which the
-next-to-last character in a font would be clipped out, but the last
-one wouldn't.  the code below deals with this.)
-
-	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.
-
-	the register allocations for startmask and endmask may not
-be the right thing.  are there two other deserving candidates?
-xoff, pdst, pglyph, and tmpSrc seem like the right things, though.
