Method quad

core/src/processing/core/PGraphics.java:2610–2618

A quad is a quadrilateral, a four sided polygon. It is similar to a rectangle, but the angles between its edges are not constrained to ninety degrees. The first pair of parameters (x1,y1) sets the first vertex and the subsequent pairs should proceed clockwise or counter-clockwise around the defined

(float x1, float y1, float x2, float y2,
