Hi guys,
When displaying velocities, I get a lot of black lines (assuming these are the negative values). When I abs it, it’s much friendlier to see, you might wanna consider doing that for the display 
And then someone will come and say “I want negatives to be black so I can see them”. 
It is possible to add an Abs explicitly, but impossible to remove an implicit Abs from the code, so I think what we are doing now is more flexible than what you are suggesting. But I will log it and we could have a checkbox to do the abs when displaying vectors as colors.
Or do a .5 offset?
