Add input String parameters to determine the name of the generated outputs.
These attributes include:
- the name of the generated output panorama
- the name of the generated output panorama preview
The base folder for these outputs remains the node's cache, only the
name of the outputs themselves can be updated.
The output attribute about the downscaled levels of the panorama is also
modified with the new name of the pyramid levels, which is a concatenation
of the generated panorama's name and the size of the current level.
- Fixed the range of the "previewSize" parameter: since its step was set
to 5000, it could only be set to 0 or 1000. It can now be set from 0 to
5000 with steps of 100 pixels;
- Fixed the case of the "previewSize" and "outputPanoramaPreview";
- Improved the description of "previewSize", and added descriptions for
"outputPanorama" and "outputPanoramaPreview".
