Ok, not sure if the title describes this in the most perfect way, which is maybe
why i've been having trouble googling and browsing the forums for something
similar.

Short history:
I am in the process of creating a VJ tool for live performances. For this I need
a bunch of on-screen controls that I want in a separate frame. So far I have
been able to use the main frame for the controls and create a second frame
that I am using as main output that will be projected.

My Problem:
The second frame holds a GLCanvas instance that i draw to for opengl magic.
However, since I am writing this framework I would like to support the other
renderers of Processing aswell (mainly P2D).

Question:
Is it possible to use the processing commands outside of the main window?
And if so, is there something like a P2DCanvas class, or would it even be
possible for me to write one?

This might be some extremly silly thing that I have overlooked, so please
forgive me in advance if so. I have tried searching but have come up short.

Thank you.
