Quick and dirty script gathers the original SVG icons from the
bitmaps_png folder and generates bitmaps at several sizes named
according to the mime type or application name. To get the names, the
script reads the kicad-kicad.xml mime package and the application
.desktop files, reconciling both to make sure all defined types have
proper associations.
