      Hi laserpilot, Thank you! Very interesting patch! i'm studing a lot.
      A question relating to the object: [jit.op @op >= >= >= >= @val 0.] What are the differences between to use 4 equal operators (multi op) , or to use only one?
      [jit.op @op >= >= >= >= @val 0.] or [jit.op @op >= @val 0.]
      for me, the result would be the same in both cases
      Thank again!

      I forget my original reasoning for that since that project is a couple years old now. I think it was just reassuring me that I'm doing it for all of the color channels ARGB. In other cases you would use 4 different operators to do different things on the color channels, but in this case since they're all the same it doesn't really matter.
