We currently have support for interpolating CGFloat, CGPoint, and CGSize. We should add a method for CGRect as well.

I recently ported my emulator to use pixels, and it's great! I love the automatic scaling to the window size.

However, I would also like to allow my users to select a scaling factor that they prefer, regardless of window size. I tried passing my own values to pixels.resize, but this doesn't do what I want.

Document should be short and contain basic information about pixiq package primitives (Image, Selection, Color, Screen, Loop) and coordinate system used by Pixiq (origin is on top-left corner, x is always before y in method signatures etc.). It should be approachable by beginner. Experiment with visual documentation - maybe create Pixel Art animated image describing basic primitives?
