simulation of pens

[slartibart70]

Hi,

i know you said 'eventually' to bring new features like pen-simulations into the library.
Any progress on this? (no, please don't feel pushed in any way, just asking about the 'roadmap')
BTW, pretty good work so far!!!

@rschroll if someone wanted to tackle this, did you have thoughts on how to implement this?
