Fast Crop filter not working properly on objects with alfa channel.

Summary:

The new Fast Crop filter uses a Composite effect with the Over operator. It is supposed to do nothing but it changes the colors of objects with transparent pixels.
A different operator should be used.

Steps to reproduce:

  • open Inkscape
  • draw an object with RGBA color #00000080
  • apply Fast Crop filter to that object

What happened?

The original object (#00000080):

After applying the filter:

Object apears as if the color was set to #000000BF.
This of course also applies to imported bitmaps making this filter unusable for cropping bitmaps with transparency.
