Implement transformation matrix to allow skewing and rotation

[mrzapp]

This would be individual to every widget, but maybe it'll be too heavy?

This sounds interesting actually and I bet many would love the feature.

The code should be something like this:

var matrix : Matrix4x4 = Matrix4x4.TRS ( transform.position, transform.rotation, transform.lossyScale );
GL.Vertex ( matrix.MultiplyPoint3x4 ( position ) );
