    initial v1  
    33There are fewer caveats for the scalers in SCI3 games than in earlier SCI32 games. The games that used an internal script resolution of 320x200 instead of 640x480 (all SCI2 & 2.1early games, and some 2.1mid games) had specific requirements for how scaling needed to work in order for picture cels to line up correctly (see the comment in SCALER_Scale for details). It is possible that there are screen items in LSL7 or other SCI3 games that also require pixel-perfect alignment to avoid rendering errors, though I don’t know of any examples offhand where you are likely to see such a resource being scaled. Other than that I can’t think of any fundamental problems with using a scaler that works better than NN and doesn’t interpolate the transparency keycolor.

    5 The only super important thing I can say is to make sure that the feature can be toggled off in the game options like the various other ScummVM enhancements, so we can offer faithful rendering for historical preservation reasons and so we can compare against screenshots from the original interpreter to verify renderer correctness. I am happy to help you learn these parts of ScummVM to implement such an option (it’s not complicated at all, just a bit spread out).

    7 It would also be preferable that this cel scaler doesn’t break ''any'' of the games when it’s enabled, including those earlier SCI2/2.1 games with special scaling, even if we decide not to allow it for some of them because it just makes them look horrible.
