udom-svgmatrix-202-t

This test creates two SVGMatrix objects and calls inverse on each. The first matrix is invertable, but the second one is not, and should throw an exception when inverse() is called. To pass, the inverted matrix must be correct, and the exception for the second matrix must be thrown. To indicate a pass the result of the test changes to green and the text at the bottom right hand corner changes from "failed" to "passed".
