New effect request for upcoming kdenlive

[Jurrasic Parker]

Hello, kdenlive Team!

First, I would like to congratulate you all on your work creating the 
best (in my opinion) opensource Linux video editor to date. I am an 
amateur video editor with zero budget and limited hardware, and kdenlive 
has always run very well on my system.

I have a small request; I've noticed that the video editor PiTiVi has a 
few video-distorting effects called Bulge, Pinch, and Swirl. I find 
these effects very useful, but the current version of PiTiVi is so buggy 
that it will not run on my old hardware. I was wondering if perhaps, if 
at all possible, similar, keyframeable effects could be ported to 
kdenlive. If it can't be done, I completely understand. But if it's 
possible, it would be greatly appreciated.

Thank you for your time.

Jurrasic.
