It's nice to see some more support for the evil plan lalo and I have
been hatching :)

That said, while pg2 will technically be a rewrite since the underlying
object model is changing, from a high level there's a lot less change
than there seems.

The new architecture pretty much completely rewrites picogui's widget,
networking, and layout subsystems. The rest, including drivers, font
engines, terminal emulation, and build system could be heavily borrowed
from.

The font engines, video, and input drivers are already just convenient
abstractions around existing libraries. Other components that might be
reusable outside of picogui, like the terminal emulation code, should be
made available as a standalone library.
