2.0b Unnecessary shader instances

[osmetanin]

Sorry, that's my mistake. As I've figured out, duplicate shader instances we created because I instantiated new Effect each time I created a Mesh. Closing the issue

That's amazing to see people digging that deep in the code :)

A nice patch would be to be able to share the signature-instance map so this problem
does not occur. That's something we might patch. But for now we just though that creating the same
shader object over and over was something people shouldn't do.

Saddly, this is a situation we can't ignore. Sometimes, it's really to much of a constraint.

This pathc could be to make the signature-to-instances map a static variable.
But I think we have to do something like a (shader) Class to signature-to-instances static Dictionnary.

That should do the trick... if you have the time to do this patch we will gladely merge it :p

Thanks for your feedback and all your good work!
