How is supposed to work the "dash_offset" when stroking paths in line mode?

* the Python help says the input value range for "set" is 1..100 while the output value range for "get" is 0..2000

* whatever the value I seem to always get the same result

Is this supposed to shift the dash pattern? Is it an absolute value or is it relative to the dash pattern length?

Assuming I have a pattern like:

"#### ## #### ## #### ##"

what do I need to do to stroke it as:

" #### ## #### ## #### ##"

OK, so the answer is: it's an absolute length in pixels, so in practice you have to compute it from the sum of the dash pattern elements and the line width.
