How do I read session props in the perspective module? I need to check and use theme changes.
I mean reading Session props from the react section in developing the perspective module.
Ohh sorry, you had module development tagged on the post as well.
Note my earlier caveat in that post - you might just want to react to the theme via CSS, not attempt to read it from JS, but 
I tested this code but it didn't work for me, I have no idea how to read css changes, or how to define a listener for these css changes.
