Extra line here

Use FIXME instead of TODO

Ditto.

I guess you don't need the ? true : false

This is duplicated, I would probably remove the previous one.

computeRecommendedWebGLFramebufferResolution could return IntSize instead of using a parameter.

FIXME

Better use return value instead of parameter.

And here too. Unless those they really need to receive an existing IntSize to be modified.

OK

Stupid mistake indeed.

Right. I'll also fix the weird characters in the comment.

Yes, compiler must be able to do the return value optimization so I agree it's better to return it.
