Returns a matrix equivalent to a flip about the x-axis.
ISVGMatrix retVal = object.flipX();
This method has no parameters.
The ISVGMatrix::flipX method post-multiplies the matrix by using the transformation [-1 0 0 1 0 0] and returns the resulting matrix.
Post-multiplies means that other matrix operations are performed before this operation.
