Good point :-)
I wonder if respecifying the source and recompiling the program is
worth it, or if we should just create a new shader object.

It is, actually. If there's no shader in use, we need to tell GL to
use fixed function again. The glUseProgramObjectARB call takes care of
that. (programId is zero when no shaders are in use).
