Fixes: #4063
Switching from an AlertDialog to only a DialogFragment.
I didn't get the AlertDialog to be sized correctly.
It also opens now directly with the right (full screen) size. When the
imageView fails to load (i.e. with an audio file) it will be hidden.
This changes the button layout somewhat.
One observation: The placeholder text "... visually impaired..." is not
quite right as a description for an audio file is not intended for the
visually impaired. But I couldn't think of a better text just yet.
Migrate to touchimageview from photoview, and adjust the touch logic to correctly handle single finger drag, two finger pinch/stretch, flings, taps, and swipes.
As before, the features are:
- Single tap, show/hide controls and media description
- Double tap, zoom in/out
- Single finger drag up/down, scale/translate image, dismiss if scrolled too far
- Single finger drag left/right
- When not zoomed, swipe to next image if multiple images present
- When zoomed, scroll to edge of image, then to next image if multiple images present
- Two finger pinch/zoom, zoom in/out on the image
Behaviour differences to previous code
1. Bug fix: The image can't get "stuck" when zoomed, and impossible to scroll
2. Bug fix: Pinching is not mis-interpreted as a fling, closing the image
3. Bug fix: The zoom state of images is not lost or misinterpreted when the user swipes through multiple images
4. Bug fix: Double-tap zooms all the way, instead of stopping
5. Tapping outside the image does not dismiss it, controls and description show/hide
