-/********************************************************************
-
- 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.
