-/********************************************************************
-
-   In this file we have GC level replacements for PolyText8/16,
-   ImageText8/16, ImageGlyphBlt and PolyGlyphBlt for NonTE (proportional) 
-   fonts. The idea is that everything in this file is device independent.
-   The mentioned GCOps are merely wrappers for the 
-   PolyGlyphBltNonTEColorExpansion and ImageGlyphBltNonTEColorExpansion
-   functions which calculate the boxes containing arbitrarily clipped 
-   text and passes them to the NonTEGlyphRenderer which will usually 
-   be a lower level XAA function which renders these clipped glyphs using
-   the basic color expansion functions exported by the chipset driver.
-   The NonTEGlyphRenderer itself may optionally be driver supplied to
-   facilitate work-arounds/optimizations at a higher level than usual.
