-    we should eventually special-case fixed-width fonts, although
-its more important for ImageText, which is meant for terminal
-emulators.
-
-    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 well-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.)
-
-    PolyText looks at the fg color and the rasterop; mfbValidateGC
-swaps in the right routine after looking at the reduced ratserop
-in the private field of the GC.  
-
-   the register allocations are provisional; in particualr startmask and
-endmask might not be the right things.  pglyph, xoff, pdst, and tmpSrc
-are fairly obvious, though.
-
-   to avoid source proliferation, this file is compiled
-three times:
