The quick fur operator now uses the new hair system. It adds a new
curves object for every selected mesh, and adds geometry nodes
modifiers from the essentials assets that generate curves. A few
settings are exposed in the redo panel, including an option for whether
to apply the modifier to generate the initial curves so that there is
original editable data.
The point of the operator is to give people a sense of how to use the
node groups and to give a very fast way to build a basic setup for
further tweaking.
