Function Matrix.invert
Changes matrix to be the inverse of its original value. Not all transformation matrices have inverses; if the matrix collapses points together (it is degenerate), then it has no inverse and this function will fail.
Prototype
void invert();
Throws
If matrix has an inverse, modifies matrix to be the inverse matrix. Otherwise, throws a cairo exception with CAIRO_STATUS_INVALID_MATRIX type.
