gollark: It won't be *exact*, being an image and all, but you could probably do "close enough". You would need a lot more resolution on the circle to display it well than the rectangle, though.
gollark: I'm beginning to think that it might be easier to just hand-write SVGs.
gollark: Here's an incredibly bad diagram. I need an image editor for Linux which actually works.
gollark: Take each pixel of the input and its X/Y coordinates, divide the circle up into an equal amount of "pixels" using polar coordinates, and map them on.
gollark: You could probably do it (with "image" meaning some pixel-y thing on a computer and not some mathematical variant), but it would look stupid.
