ellipseMode()

Set how the (x, y) and size arguments of ellipse() / circle() / ngon() are interpreted.

• CENTER (default): (x, y) is the center; w/h (or d) are the full width/height (diameters).
• RADIUS: (x, y) is the center; w/h (or d) are radii, so the shape is twice as large as in CENTER.
• CORNER: (x, y) is the top-left of the bounding box; w/h are its width/height.
• CORNERS: (x, y) and (w, h) are two opposite corners of the bounding box.

Follows ellipseMode() in p5.js. Resets to CENTER at the start of each fabDraw(); scope a change with push() / pop().
