Previously, touching a touch screen would advance the presentation to the next page no matter the cursor position. With this patch, this behavior can now be changed by a new option 'Touch navigation' in 'Preferences->Presentation':
- "Tap left/right side to go back/forward": Tapping on the left(right) half of the screen makes the presentation go to the previous(next) slide.
- "Tap anywhere to go forward": Tapping on the screen makes the presentation go to the next slide, no matter where the screen is being tapped
- "Disabled": Screen tapping doesn't do anything.
The actual action happens on mouse-release. For touch screens this means less interference with swipe gestures (which also allow to go to the previous/next page).
