Mobile full screen example

[twpayne]

This PR adds a full screen example suitable for devices that don't support the Full Screen API, e.g. mobile devices and IE.

Hi @twpayne, this looks good and can be merged.

I would have preferred a separate PR for the geolocation changes as these aren't directly related. Feel free to merge this, though.

Looks good to me.

Personal opinion: it's more important to have separate commits than separate PRs.

I would as well. The changes are related because ddb295c depends on be7228f (link). Trying to maintain separate PRs gets really complicated really quickly. If you don't mind commits taking 2 days (or more) instead of 2 minutes to be reviewed then it's OK that development should be slowed down by 2 * 24 * 60 / 2 = 1440 times. We all have years to spare, right? At least separating commits means that the changes are clear and we can still merge the non-controversial improvements.

This comment is not really encouraging to reviewers. One thing I've learned in 6 years of OpenSource community work is that patience is a virtue when it comes to waiting for code to get reviewed. And sometime the code changes and improves while waiting, because of the extra time you get to think about it. Not all bad.

The geolocation recenter does not work on http://ol3js.org/ol3/master/examples/mobile-full-screen.html
geolocation.exports needs to include ol.GeolocationOptions
