Description

Sets/gets the width of the overlay quad in meters. By default overlays are rendered on a quad that is 1 meter across.

Overlays are rendered at the aspect ratio of their underlying texture and texture bounds. Height is a function of width and that aspect ratio. An overlay that is 1.6 meters wide and has a 1920x1080 texture would be 0.9 meters tall.
