-
- 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.
