When zoomed in, the thumbnail previews of MyPaint brushes in the official GIMP releases appear heavily blurred and pixelated. Fortunately, it is highly feasible (and relatively simple) to improve their rendering quality. By switching the source assets from PNG to SVG format, the thumbnails can scale cleanly. Implementing this requires only a minor code change: adding a single new function in /app/core/gimpbrush.c and replacing the existing PNG assets with SVGs in the /mypaint-data/brushes/... directory.
