Nice!
As an aside, I have noticed a problem: if I click on the "OK" button
for the shader demo, while the demo is running, I'll get a second
instance of the demo. The cube in the first instance freezes, and the
cube in the second instance spins faster.
Worse, when shutting down the demo, I get into an infinite error
situation and have to shut down J from the outside.
I think the issue here has to do with the use of the timer. I don't
think we have an option to make timers in a locale, and we haven't
defined any dispatching system to support multiple locales. Perhaps
the thing to do here, until we can come up with a better approach, is
refuse to run if the timer is already in use?
What do you think?
Thanks,
