Overview

A chingu trait providing easier handling of the “retrofy” effect (non-blurry zoom) Aims to help out when using zoom-factor to create a retrofeeling with big pixels. Provides screen_x and screen_y which takes the zoom into account Also provides new code for draw() which uses screen_x / screen_y instead of x / y
