Comment (by DanielSWolf):

 As expected, upscaling proved to be much harder than downscaling. The
 tricky bit is not to write a good 2x scaler (there are a many good 2x
 scalers), but to write a scaler that gives consistently good results at
 any scaling factor between 100% and 200%.

 It took some tweaking, but I've finally arrived at a version I like:

 So now, I have working POC code for up- and downscaling. Next, I'll need
 to clean up the code and optimize it for speed.
