Please, add the ability double tap in PDFViewPager Android component:
- initial double tap to zoom in the current page only (with default of x2) with specified factor by developer
- when already zoomed with double tap or other (for example pinch zoom) to zoom out to initial scale
- optionally (as this is not related to double tap) the ability to set if we want the page to automatically zoomout when current page is changed (it is still cached to left and right as zoomed and only when it is re-instantiated is using initial scale)
Currently in order to add the double tap zoom I need to create my on Pager, Adapter and extend the PDFPageView and not use all the goodies you've already implemented in PDFViewPager
