0004 Subject: [PATCH 1/2] [macOS] allow finding plugins outside bundles
0005
0006 This allows to load mlt plugins from install directory when the
0007 .app is missing Plugins and Resources locations.
0008
0009 The patch is not robust, its designed to change from one static
0010 location to another when running krita.app from a kritadev environment
0011 when the bundle dirs are missing: this only happens when running
0012 krita.app from install directory after building.
0013
0014 changes are:
0015 i/bin/krita.app/Contents/Plugins/mlt -> i/lib/mlt
0016 i/bin/krita.app/Contents/Resources/mlt -> i/share/mlt
