Paused main loop still calls requestAnimationFrame

[J Decker]

This GUI library I'm porting has a status of whether it wants to draw continuously, or wants to just notify the system to do a single draw after a change.  (a User form GUI doesn't change that often)

There used to be a function  emscripten_request_animation_frame  But that doesn't seem to exist in headers anymore.... 

So the only way I can seem to get the desired behavior is to use pause_main_loop() and resume_main_loop().  I issue pause_main_loop basically every time a draw happens, but I noticed in profiling that animationloop is still being dispatched, just gets an early return in the emscripten handler I suppose....

I would have gotten rid of the main_loop entirely, and instead just call requestAnimationFrame myself; but like I said there's no request function in current include/emscripten/* headers.
