A section on the spaces would be very useful. There exists world space, data space (which is basically world space + offset and rotation), and screen space. There's a help func to map from screen space to world space that's useful for interacting with graphics.

A section on using it interactively would be very useful, similar what's on wgpu docs: https://wgpu-py.readthedocs.io/en/stable/gui.html#using-wgpu-interactively

basically:

• in jupyter
  • if nothing special is done, uses remote frame buffer, display in cell output or side
  • %gui qt before importing fastplotlib will use qt
  • Figure(canvas="glfw") should force glfw
  • Do not mix or switch between gui backends, ex. if you want to use qt use %gui qt at the start of the notebook, and then do not try to force another backend such as jupyter_rfb (remote frame buffeR)
• in ipython
  • can use qt or glfw, same was as above

I'm going to merge but those warnings and images have to be fixed.
