The potential for breakage is too high, and I am working on an
alternative solution that will be better long term.
Prewarming is still used for kittens launched via keybindings
The color table attributes are never used in a type checked
environment, only via setattr/gettattr so dont create individual
get/setters for them. Reduaces the import time for this module from 2ms
to 0.7ms
Since attribute access is implemented via __getattr__ there should be no
performance implications for normal attribute access, as __getattr__ is
only called if normal attribute access fails. setattr becomes slightly
slower but that is done very rarely.
Now the time for importing the kitty.config module has been halved, from
16ms from 32ms on my machine. Also, the new architecture will eventually
allow for auto generating a bunch of python-to-C boilerplate code.
