[Sidefx-houdini-list] ROP asset question

ROPs are kind of tricky because they have to hook into SOHO, and new soho
properties get added constantly, so keeping otl ROPs up to date quickly
becomes a nightmare.

Galleries and presets are one nice alternative to otls. They build UI, set
values, and can be applied to the latest factory ROPs. You can apply a
gallery to any ROP node from a button with either a callback on a button or
a callback on a menu of some sort.
