Source used for scaling attempts
SUMMARY
There currently is the inherent issue of having blurred results when using
fractional scaling. However, there are better and worse algorithms for that.
Also one might think about completely moving away from simply scaling things up
and use pixel perfect graphics, maybe derived from svg graphics instead.
I did some short test with GIMP and different algorithms for upscaling. See the
attachements. It is clearly visible that NoHalo and LoHalo reduce the
blurriness in comparison to Cubic or Linear. I don't know which algorithm is
currently used, but there might be potential for improvement there.
I might have filed this for the wrong product, please check, whether this is
correct.
