aeq has custom types for 'Property', 'Comp' and 'Layer' (among others). Should some of our
get functions return the aeq types for these, as opposed to native AE elements?
The benefit is that it's easier to integrate into the rest of aeq, or to chain commands. The negative is that it will break existing tools, and that maybe user just wants the native property directly vs the aeq type?
