Everything should be accesible by python in an easy way.
Will make life much easier for everybody.
Leave the core alone, bug fixing / interface inconsistency fixes is the priority NOW.
My .2 cents
Everything should be accessable in C++.
I wouldn't mind comments like this
if what you were talking about actually *worked properly*
in the current versions.
The code is currently written in C/C++ so making a libary for that
would be far simpler, at present, than screwing with the half baked
python interface. Plus you'd have better speed and more low level control
to improve rendering times for big jobs.
Just my opinion.
