rectMode()

Set how the (x, y) and size arguments of rect() / square() are interpreted.

• CORNER (default): (x, y) is the top-left corner; w/h are the width/height.
• CORNERS: (x, y) and (w, h) are two opposite corners of the rectangle.
• CENTER: (x, y) is the center; w/h are the width/height.
• RADIUS: (x, y) is the center; w/h are half the width/height.

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