In the free software community, GPUs are sometimes absent or
nonfunctional.  That's because many of them require the installed
operating system to contain nonfree software, and some of us refuse
to install a system which contains that.

What this means for Emacs is that we need to keep it working well
on the machines where some or all of the GPU's functionality is absent.
(I won't say "missing".)

Someday we will have processors that with GPUs that don't
require users to install nonfree software, and that problem will
cease.  But I don't expect that to happen next year.

We should take care not to add features to Emacs which _need_ the
acceleration, because they won't work well on the machines without
graphics acceleration.
