e22a75de99 Rewrote the handling of thumbnail creation for KQ6 Windows in rev #50600, so that it recreates the screen buffer like the other workarounds above it (thanks to LordHoto for pointing this out)

d163686d2d Document that the current Hercules mode thumbnail scaler code is pretty much aimed for SCUMM games.

9bb92eba9e Fix for ARM Normal2xAspect scaler that was causing crashes when the screen 
'shakes' (such as when the head/bomb goes of at the start of sam'n'max).
Was overwriting the end of the screen when asked to plot a non-multiple of
5 lines.

edaa4a0422 MIPSpro compilation fixes / workarounds (from a patch by Rainer Canavan) 
The hashmap.h change is ugly, but so far the only thing found to work. Suggestions for a better "fix" appreciated!

816bd9a7ea Add ARM code version of Normal2x scaler. 
Add ARM only aspect ratio correcting version of Normal2x scaler.

Make WinCE port use Normal2x by default if the screen is large enough.
Make WinCE port use aspect ratio correcting version if panel is hidden.

02ac46565b Tweak the hq2x/hq3x a little bit (interpolation code is little bit shorter, faster and easier to read... but 70+% of the time is spent on computing diffYUV etc. anyway, so I guess this a bit pointless... whatever... ;)

4098ff66aa Removed use of LUT16to32 in HQx asm versions, replacing some MMX code with 'plain' x86 code. Advantage: got rid of a 256kb table (reduces cache load, so over here the code is about as fast as before; in particular, since the affected interpolators are not used that often, it seems). Moreover, the new code is more accurate than the old ASM code, which actually differed from what our C++ HQx did (sacrificing precision for speed, i.e., cheating ;-)

16e7a7cd30 Turned two vars of the HQ2x/HQ3x ASM implementation into global vars, to make it possible to adjust them for 555 vs. 565 mode (555 mode is still a bit buggy, due to the interpolation code they use)
