Description
Summary
Not only is picture preview in Custom Picker lacking in zoom (see #5701), it is also annoying slow to display the picture.
Perhaps we could just call external default gallery/image viewer app (via intent) to display that picture on long-press?
That would be much faster, fix the related zoom bug, give user the choice, and probably reduce the code.
(Or at least use some reasonable library / implementation instead of whatever is being used currently.)
Steps to reproduce
- Open Commons app
- choose
+to add picture, and choose 3rd option (Custom selector) - long press on some picture to preview it
Expected behaviour
Picture displays immediately (on this class of hardware!), just like it does in any other picture viewer (stock gallery, Fossify Gallery, Ghost Commander viewer...) i.e. under 0.1 seconds
Actual behaviour
spinner appears and spins for more than 2 seconds before picture is shown. That is more than 20 times (2000% !) slower than normal!

To add the insult to the injury, the viewer code does fancy fade-in effect, thus making picture display intentionally slower by some 0.2 seconds or so more...
