  • gimp-painter

    • patch added MixBrush,G-Pen tool and the color management for GIMP.

    • Why: is not the patch put in the Ubuntu (main)package?

      • The upstream project is release-suspended status. The patch is in "private" mode (Still maintenanced, but not published).
      • Of course, GPL allow branching and undertaking the yet another -painter project, but that patch (and GIMP source code) require experienced craftsmanship. So ,that is too much to handle for me.
