+    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.
+
+   to avoid source proliferation, this file is compiled
+three times:
+	MFBIMAGEGLYPHBLT	OPEQ
+	mfbImageGlyphBltWhite	|=
+	mfbImageGlyphBltBlack	&=~
+
+    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.

+       field.  the GC is now in an inconsistent state, but we'll fix
+       it as soon as PolyFillRect returns.  fortunately, the server
+       is single threaded.
+
+    NOTE:
+       if you are not using the standard mfbFillRectangle code, you
+       need to poke any fields in the GC the rectangle stuff need
+       (probably alu, fgPixel, and fillStyle) and in devPrivate[mfbGetGCPrivateIndex()].ptr
+       (probably rop or ropFillArea.)  You could just call ValidateGC,
