Post-multiplies the matrix by a uniform scale transformation and returns the resulting matrix.
HRESULT scale( float scaleFactor, ISVGMatrix **ppResult );
- [in] The scale factor to apply along the x-axis and y-axis.
- [out, retval] The resulting matrix.
Returns S_OK if successful, or an error value otherwise.
Post-multiplies means that other matrix operations are performed before this operation.
