I am not saying this without reason, you know.. Normally when you want to
partition software into idnependently loaded components you create a
well-defined interface for them to communicate over and make sure they
stick to it. Then you can mix versions freely. If you do not have a
well defined interface then your only recourse is testing different
versions for compatibility. The problem is that for a driver a signficant
part of that interface is hardware interface of which we do not have full
understanding, and as for testing I do not know who and where is going to
do it. In fact, I do not even know a good app to test GL functionality,
not perfomance (i.e that all calls do as they should and do not crash the
machine). I know some people proposed kernel driver that does everything,
but I would think this will either double the work or will not be
compatible with OSes other then Linux. Or both.
As for X11 libraries they were designed to be compatible across different
X implementations, so different Xserver versions should work ok. For
example each time you connect from an Xterminal the programs running on
the remote machine use libraries different from ones in your Xterminal
(if it has any.. though all that I've seen do). I am saying "should"
because though core X protocol is the same there are extensions that can
break. I remember some issues with DGA way back, but I never used it so I
do not know for sure.
Does this make sense ?
