alright so this is a lerp, all fine, no complaints here
x * a + y * (1 - a)
but what a lerpaderp is this?
x * a + (1 - x) * (1 - a)
@namark Uh oh...so not just a math problem? What is lerp? I thought you were making some kind of commentary about the math looking like babble..I may have made a wrong assumption here...
It's a weird programmer slang for linear interpolation

I'm trying to make sense of some code this idiot wrote here:

@Lwasserman what is it?
maybe lerp(x, 1-x, a)
or maybe lerp(a, 1-a, x)
or something completely different?
