Ah, thanks I didn't know there was a LuaJIT list now. I will have to
post there in the future.
I have tried the offset by one method but again run into issues with
the confusing nature of it. If an end user has to make a native call
(eg. OpenGL) they have to remember to offset the data which is
unexpected. A solution is to wrap all external API calls, but again:
performance hit when making lots of calls. That's really the main
issue with all of this, it's just (inconsistent and confusing) or
