Purpose

Draws additional contours for GVRContourOverlay

Usage

Connect the module before the GVRContourOverly in the scene graph and specify name and ID.

Details

The contour is calculated in a GLSL shader using a 4-neighbourhood in screen coordinates. Thus, zooming in does not affect the contour thickness.
