Extrude material no longer an option in three.js r72

[elifer5000]

Up until r71, TextGeometry (itself based on ExtrudeGeometry) had the option to select different materials for the front and the extruded faces. The code below would be able to produce:

var materialFront = new THREE.MeshBasicMaterial( { color: 0xE94042  } );
var materialSide = new THREE.MeshBasicMaterial( { color: 0x000000 } );
var materialArray = [ materialFront, materialSide ];
var textMaterial = new THREE.MeshFaceMaterial(materialArray);

var textProperties = {
        size: 5, height: 1.0, curveSegments: 3,
        font: "helvetiker", weight: "normal", style: "normal",
        bevelEnabled: true, bevelThickness: 0, bevelSize: 0,
        material: 0, extrudeMaterial: 1
    };

var textGeom = new THREE.TextGeometry( "100.0", textProperties);
var textMesh = new THREE.Mesh(textGeom, textMaterial );

I found this commit in the project's github where the option to set the material and extrudeMaterial was removed, with no apparent alternative way to achieve the same result. Now in r72 all the faces have the same color (the one from materialFront), like this:

Samples:
JSFiddle with r72 - side color is missing
JSFiddle with r71 - works ok

It appears the changes toExtrudeGeometry implemented here need to be reverted -- if possible.

i don't understand how to use a a diferent material for the extrudeMaterial this doesn't work anymore http://jsfiddle.net/ma3wtuLx/7/

@SenninSensei It seems to work: http://jsfiddle.net/ma3wtuLx/9/. r.74dev

It seems these are not working though.

material: 0, extrudeMaterial: 0

material: 0, extrudeMaterial: 0

Yes. It appears to be hardwired, now. The first material is for the front, and the second material is for the side.
