Glass or Bevel

Creates a pretty simple (yet cool) smooth glass or bevel effect. Can work with alpha/mask contour as well as selection. Have fun!

P.S.: Sorry for the awkward plugin name. Couldn't make up anything better.

Example:

History:
v1.03: The "Gloss Contrast" parameter added
v1.02: Smoothness = 0 was not possible
v1.01: Fixed working with mask contours
v1.0: Initial release
