issue with getCameraMatrix()

[kalwalt]

Actually the getCameraMatrix()

artoolkitX.js/Source/artoolkitX.api.js

Lines 412 to 414 in a06cb35

	ARController.prototype.getCameraMatrix = function (nearPlane, farPlane) {
	return artoolkitXjs._arwGetProjectionMatrix(nearPlane, farPlane);
	};

call the exported function _arwGetProjectionMatrix but we have already a getProjectionMatrix in ARX_additions.js

Maybe we should use this?

[kalwalt]

should be:

ARController.prototype.getCameraMatrix = function (nearPlane, farPlane) {
        return artoolkitXjs.getProjectionMatrix(nearPlane, farPlane);
    };

Does it correct?

Discussed here: #23 see the comments in the code review. I wil remove the function from ARX_additions.js because already in artoolkitX.api.js
