Horizontal scrolling for manga pages

[kisokos03]

Describe your suggested feature

Issue:

• Taller aspect ratio mobile devices means zooming/fitting to height lets you read more comfortably, using more of the screen.

• In the horizontal "paged" viewing modes, zooming creates issues, mainly turning pages accidentally, or not being clear which half of the page you're on at any given time.

• Vertical pages eliminate accidental turns, but still make it impossible to know where on a page you're on (after moving back a page for example)

• Vertical scrolling removes both issues, but introduces another, needing to scroll back to the start of each new page manually.

Each current viewing mode has its problems with zoomed in pages.

Proposed solution:

• Adding a horizontal version of webtoon-like scrolling, for page by page manga. This would allow for zooming in and making use of 100% of your screen, without introducing issues with pages.

I think the best way to implement the relevant settings is two new options in the quick settings, which are only active when webtoon is already selected. A toggle for "horizontal webtoon mode", and one for "left to right" to accommodate any potential left to right comics.

how does it not create the same exact issue as vertical scrolling? Now you need to find the left edge instead of the upper edge. What I think is the actual problem here is accidental scrolling while zoomed. That shouldn't happen. Theres already an issue for that: #1052
