[Neko] neko call to c function when embedded

[lee at designrealm.co.uk]

Hi Janko,

That's fine, I know what it's like to want to build your own engine.  
NME uses SDL as a dll, so I think it should be okay, license wise.  
Also, NME uses the SGL extension, so transforms such as scaling,  
rotation and alphas are also doable. If Allegro is your thing, you  
could also consider using my nGame library, which wraps 100% of the  
Allegro library, though I've not built a framework around it, so you'd  
have to use it as you would use the Allegro library in C, only within  
haXe instead.

I'm always tinkering with game engines, and at some point, I'd like to  
make a decent 3D engine wrapper, only I don't fancy doing that for a  
library you'd have to pay for. Plus, it's important to me that the  
engine is cross-platform...

Anyway, good luck in your work, and please feel free to post any  
questions to the lists. We're always available to answer questions.

Regards,
Lee
