athrxx 70414a0b87 SCI: make upscaled gfx driver for KQ6 Windows 
- The main purpose was to move more upscaling logic out of the engine
- This actually contains various precision fixes to the hires code. There
were some comments about being unsure what to. I think I managed to
fix all of these, although it shouldn't make a visible difference, since the
workarounds worked as intended.
- It does actually fix a very minor glitch: The portraits were vertically off
by one pixel. And the opening AVI video is probably also vertically fixed
by one pixel (although the video display in the original is not done very
well, anyway).
