Need a glPolygonOffsetFill like to improve rendering of filled polygons having a wireframe about jgl HOT 2 CLOSED

Native Polygon offset fill (JOGL)

Missing Polygon offset fill (jGL)

from jgl.

Reading this opengl page about polygon offset shows an alternative way of rendering polygon edges : using glDepthRange allows shifting a bit the edge geometries while processing depth

// Draw underlying geometry
glDepthRange (0.1, 1.0);  
drawPolygonFace();

// Draw overlying geometry
glDepthRange (0.0, 0.9); 
drawPolygonWireframe();

This circumvent the jGL limitation of the missing glPolygonOffsetFill function. The ability to build geometries providing such rendering trick is added to EmulGL, the Jzy3d integration of jGL.

All Wireframeable objects in Jzy3d now enable this rendering trick to let jGL integration work.
