I just happened upon a link to those free KPT plugins I was supposed to get with my purchase of Paint Shop Photo Pro X3.

Direct Link to plugins:
They install in the default plugin folder here (Windows 7):
C:\Program Files (x86)\Corel\Corel PaintShop Photo Pro\X3\PSPClassic\Languages\EN\PlugIns\KPT
User Guide PDF files are there too:
C:\Program Files (x86)\Corel\Corel PaintShop Photo Pro\X3\PSPClassic\Languages\EN\PlugIns\KPT\metaos\User Guide
1. Equalizer (blur/sharpen)
2. Goo (warp brush)
It's like Mehdi Projection.
There's also MuRa Perspective Tiling.
Both are free plugins.
All in all, not real interesting.
Wiki has some info on the KPT plugins.
Not much info at Corel.
