Nile and the graphics engine Gezira written in Nile was quite independent
from Squeak. Vanessa made a VM plugin for the C-version of Gezira runtime,
and the bindings code issues Gezira requests from Squeak. That part can is
reusable. But going through the VM plugin had some overhead, and also
Gezira does not on purpose provide optimization for common cases or special
cases (such as filling an integer coordinate rectangle with a uniform
color, etc.) so performance characteristics was not always a win.

There was other comments about JITting. It is potentially a great idea but
it'd be a quite effort to make sure the multi core execution (or even using
GPU) sane and efficient.
