Spherical to cubic to spherical conversion 1.1

The Spherical to cubic to spherical conversion plugin can ease the retouching of equirectangular/spherical panoramas.
The Spherical to cubic to spherical conversion filters will map the top and bottom of the panorama to flat planes so that you can easily edit them. Then you can map the retouched parts back to spherical/equirectangular again in order to apply the edited parts to your original panorama.

System requirements:
- PhotoShop

Enhancements:
- The filters will save their settings to a file called spherecubic.ini, to make sure the settings are remembered. The settings file will be saved in the same folder as the plugins.
- Added options to only extract Zenith or Nadir.
- Added options to rotate/spin the projection. This is very handy if you want to line up floor boards or other linear patterns.
- Added Express versions of the filters for quick conversions without any options. These are ideal if you want to use the filters inside Photoshop actions.
