Embed IPython
=============
Start napari and land directly in an embedded ipython console with qt event loop.
A similar effect can be achieved more simply with `viewer.update_console(locals())`,
such as shown in https://github.com/napari/napari/blob/main/examples/update_console.py.
However, differently from `update_console`, this will start an independent
ipython console which can outlive the viewer.

from IPython.terminal.embed import InteractiveShellEmbed
import napari
# any code
text = 'some text'
# initialize viewer
viewer = napari.Viewer()
# embed ipython and run the magic command to use the qt event loop
sh = InteractiveShellEmbed()
sh.enable_gui('qt') # equivalent to using the '%gui qt' magic
sh() # open the embedded shell
# From there, you can access the script's scope, such as the variables `text` and `viewer`
