Description

When a Python Processor is added to the canvas, it is quite slow. Especially the first time a Processor of that type is added. A lot of actions take place in order to enable that. This needs to be made faster. This may be done either by performing some of the actions more eagerly, or they may be done in a background thread, such as using an @OnAdded annotation etc.
