Description:

Plasma2 is a heavily improved version of an old GIMP plug-in Plasma by
Stephen Norris generating cloud-like images known as "the plasma
fractal".

Brief list of fixes and improvements against original Plasma:

- Several new generator options, including the possibility to generate
original Fractint-like and Norris-like plasmas,
- Can generate tilable images (much better than Plasma +
Make_seamless),
- Switching tilability on/off modifies the image only as little as is
necessary to achieve desired effect,
- Can directly map to a gradient (better than Plasma +
Map_to_gradient),
- Can do a gradient-remix map,
- Better handling of grayscale images (and is 3× faster on them),
- Buttons to revert/reset settings.
