Bug 458950

Issue:
Webtoons (korean comics) are often arbitrarily cut up into small images which are then presented as a continuous stream, when viewing these files in okular, the small gap between successive pages ruins the experience as it cut's up texts and images into separate parts. 

Examples:
https://toonily.com/webtoon/princess-villainess/chapter-1/
Where pages are cut up into many constituent images but displayed as a continuous stream with no gaps between subsequent pages, resulting in a much better experience.

Tachiyomi is an android app that supports reading webtoons, and they have a mode where all images are stitched together into one continuous stream. 

The Request:
Okulars continuous mode with an option to not have any space between successive pages should produce the same result.
