Comment 3 for bug 170910

Please, put only one request for tracker entry, in this case
it should have been one for fuzzy shadows and another for
perspective tool.

However, both are duplicates of old existing entries:

- perspective tool:
[ 1079582 ] Two-Point Perspective Drawing
[ 1012134 ] perspective/warp transformation envelope
[ 1005753 ] RFE: Perspective grid

- fuzzy shadows:
[ 863380 ] Implementation of SVG Filters, specifically BLUR
