In my vision you could choose arbitrary number of these including the same 
item twice and then apply different curves to both instances. I'm not 100% 
how that can be implemented tho.

They would all have range of 0.0...1.0 just like random, velocity etc now in 
SVN.

All these calculated axis would be a sort of custom. Allowing a free formula 
type is an option as well but It may be harder to implement.

I mean both. The dream is that paincore would only need to worry about 
painting a stamp at a given event, the "where?" part is all handled by paint 
core. The distance in this case is the stamp spacing.

Replicated? It's paint cores job to provide these two features and any other 
numerically controlled options and possibly expose their control values for 
event mixed influence.

Theres a check grid now in SVN. In my vision in tool pane each option that 
supports it has a checkbox to turn dynamics on and off and a button to curves 
about that specific parameter. Additionally there are sliders for scaling the 
dynamics as a whole for quick adjustment. If you load a tool the changes made 
are forgotten. They are just adjustments to the current ie paintbrush, where 
as changes in curves create and "unsaved" tool that can be marked that way so 
the user knows that they need to save it either as a new tool or overwriting 
the parent.
