Ability to disable the automatic zoom out when pinch end.

[jdanthinne]

Is your feature request related to a problem? Please describe.
I'd like to zoom in very deep in the image, but as the pinch end, the original gets back its original size, so I can't zoom more.

Describe the solution you'd like
An option to disable the revert back to original size.
As a bonus, an option to double tap to zoom between scaledToFit and real size (100%).

Thank you for the suggestion. I have begun implementing this on the add-zoom-options branch. It is very buggy right now, as I am still figuring out how to calculate the new anchor position, along with some animation bugs.

Hi, I'm interested in this feature too. How can I test this branch locally?
