So, with 50% or more of the registered defects being OpenGL related, this
is the area that needs work most. Fabian has stated that some of this is
due to supporting multiple versions of OpenGL. Doesn't sound like a hard
decision to me.
And to inflame some people even more, I'll point out that it's not about
supporting older laptops; it's about supporting CHEAP laptops. There is a
very big difference. Both of my Mac laptops - an eight year old PPC and a
six year old Intel - run Stellarium great. Better than 60 FPS. No
trouble. These are old laptops. My work laptops are only leased for three
years, and any more two is common.
Now, as we do not have active contribution from any OpenGL developers, the
point is largely irrelevant, but, if we did have them, the we'd really want
to decide what we want to do: continue to support cheap laptops, or be a
world-class Astronomy app.
