488717 - Implement a smarter form of toggle zoom for touch tablets

Status: NEW

(Firefox :: Tabbed Browser, enhancement)

For two finger tap gestures on win7 tablets, it would be nice if we had a form of zoom toggle that would pan the view to the area of the page the user tapped when zooming in, and zoom the page all the way out to a "best fit" zoom level. For example:

1) open a large page (like tinderbox)
2) tap the view once
[page zooms in to a "best fit" level] 
3) find an area of the page you would like to zoom in on
4) tap that area
[page zooms out to 100% and centers on the pivot of the tap.]
5) tap again
[page zooms back to a best fit.]
..

AFAICT, we currently don't have the right set of commands to pull something like this off at this point.

Felipe, more to chose from, we can go over open bugs at the end of the summer. I'll be happy to take some of these back if need be.
