Take (real) constant gain into consideration for result calculation #28
This limitation that persisted almost since the beginning could be seen as bug.
If a transfer function has a constant gain different than 1, then the result TextBox will neglect that gain.
For example -2/(s+1) has a constant gain of (-2), which will scale the plot by 2 and turn the phase by 180°.
The result TextBox will simply show the contributions of the transfer function 1/(s+1), as if the factor (-2) wasn't present.
