[gschneider] 40426: - Fix the coordinate manipulation order for AlphaBlend, BitBlt, GradientFill, ExtTextOutW, PatBlt, StretchBltMask and TransparentBlt - The correct setting order is: calculation of base coordinates, conversion to device units, offset by dc origin; thanks to Timo for this hint - Misc: remove unused variable in BitBlt, fix a comment in PolyLine

Log:
- Fix the coordinate manipulation order for AlphaBlend, BitBlt, GradientFill, ExtTextOutW,
PatBlt, StretchBltMask and TransparentBlt
- The correct setting order is: calculation of base coordinates, conversion to device
units, offset by dc origin; thanks to Timo for this hint
- Misc: remove unused variable in BitBlt, fix a comment in PolyLine
