Web Workers and Canny Pruning about jsfeat HOT 2 CLOSED

they way web workers implemented now it doesn't allow u to share memory buffers without copying. this is super slow so i'm not planning to spend time on fighting with it. u can still write wrappers around required methods to spawn tasks.

HAAR cascade face detector uses Canny pruning here:

For reference, i tried this out... using webworkify -- and wasn't able to get it to run faster than a non-workerized version ☹️

the difference was pretty dramatic. I'd guess it's the memory buffer copying overhead as @inspirit says, since there's not THAT much else going on here.
