Buttons on the toolbar are all 20x20, sizes that fit the historical 96dpi of old screens. DPI-aware Cartool needs higher resolutions buttons, and the current solution is to rescale them by integer factors, using classical nearest neighbors interpolation.
There are however much better solutions to upscale bitmaps, like Eagle, hqnx or xBR algorithms that would be nice to investigate / implement.
