Hi Alan,

thank you for your patch. I have a few, probably dumb questions:

* Isn't the your new integrator filter the same as a pi-simple-controller with Kp=1 and no min/max clamping?
* What would you think about extending the exponential filter to make it behave like a high-pass or low-pass like
<type>low-pass</type> or <type>high-pass</type>. That would not double existing code.
* What is the purpose for adding alias names for existing filters?

Post a diff or the modified files or a link to a tarball here and I'll have a look.
Probably a good start for me to get back into the loop after almost two years of absence...


Thanks Torsten.
At some time I will need to add a means of initialising the Integral filter to a  <property>.
