-
-   In this file we have GC level replacements for PolyText8/16,
-   ImageText8/16, ImageGlyphBlt and PolyGlyphBlt for TE (fixed) fonts.
-   The idea is that everything in this file is device independent.
-   The mentioned GCOps are merely wrappers for XAAGlyphBltTEColorExpansion
-   which calculates the boxes containing arbitrarily clipped text
-   and passes them to the TEGlyphRenderer 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 TEGlyphRenderer itself may optionally be driver supplied to
-   facilitate work-arounds/optimizations at a higher level than usual.
