Colors interpolate when transforming (0.4.0)
Hey! Found another bug with version 0.4.0.
In this picture I've just pasted a 6x6-tile sprite. Here's what it looks like originally.
If I scale it down so its dimensions are 3x3 tiles, I have some unwanted colors in the result that weren't in the original.
The original has 14 colors, but after the transformation, there are 40 colors! I'm actually surprised as I'm writing this, because I thought there were only a few extra colors. I ran it through a color-counting program, and I guess it's a LOT more than I thought. Almost every color has been interpolated with adjacent colors, making them all slightly different.
Would highly advise against scaling anything in this version if you're working with a fixed palette. I don't believe this happened with the previous version, I definitely would have noticed it.
