innerWidth: return type unified

[ericaro]

all (width,height, outerWidth, outerHeight, innHeight) dimensions have a return type "Number" but innerWidth which has a return type "Integer".

I don't see the reason for that, so I guess this is a small mistake.

Eric,

👍 , although it's not actually a mistake because the method originally could only return an integer. At this point there are cases where it may not be integer so we should clarify it.

We should probably add a note about that, not just change it?

It's not our change that made it more likely to return non-integer values, it's that screens are getting higher resolution and the browser is returning "fractional pixels" more often, for example.
