Draft: Pixel-perfect Algorithm

Ken Lo requested to merge kenlo/krita:pixel-perfect-settin into master

Currently Krita from KDE doesn’t have a Pixel Perfect option, the name for an algorithm that visually smoothes out pixel art curves. The idea here is that whenever the user ends up with a L-shape with this option, it would smartly remove corner pixels so that the overall curvature looks less blocky and more clean. By introducing this functionality, Krita users looking to utilize the pixel art functionalities alongside with Krita’s features can have an easier time controlling the precision and aesthetics of their pixel art creations.

Currently in the research algorithm and implementation phase, added a placeholder option under sharpness in brush editor.
