Re: [AD] Allegro JavaScript port using Emscripten (First version complet

I just profiled this on my sluggish laptop, an older E350 machine, and nailed around 8fps on average.

I'm not too familiar with profiling HTML5, but the main culprits appear to be:

56% in WCF__flushMessageQueue()

This is an internal, and only around 1% was lost to call-outs. My uneducated guess is that there's a tonne of message handlers registered that it's iterating through, or an equally enormous amount of unhandled messages.

16% in _glDrawArrays()
This is in skater_r.js.

This is a very nice beginning. I am in favour of already adding this
to the development branch of allegro, or to a separate branch, to keep
Max's good work safer from getting lost.
