That's right. Gui will remain in python. Algs will mostly be python,
unless they benefit from the speed boost of the native c++ code. All
the algorithms which rely on external apps will remain Python.

If anyone's curious, here's a video demonstrating the current state of the work:

Not much to get excited about from an end user's perspective yet, but
what you see here is:
- a native buffer algorithm, fully written in c++
- background algorithm execution using task manager
- the new API which uses a dictionary of algorithm parameters
- a demo of dynamic property based parameters (will be exposed via the
UI just like data defined symbols/labels/etc)
