Unsharp mask for virtualdub

Hi, after some discussion at virtualdub forum about unsharp mask crashing I thought I'd post here
v1.4 almost always crashes, V1.3 works ok
I also had a bit of a play with the code
Updated it to use the latest sdk
Added some yuv support
Put the filter and source on sourceforge https://sourceforge.net/projects/virtua ... askfilter/
If that's a problem, let me know and I can take it down
Atm, there's still some optimization that can be done to speed it up and when I get time I'll put that up as well

That's great, thanks! I'll check it out and link it at my site. Lots of my old Vdub filters need some freshening up so your contribution is really welcome.
