Images not resizing to fit the screen in scrollview about readium-shared-js

[danielweck]

See candidate fix in feature branch:
https://github.com/readium/readium-shared-js/tree/feature/scroll_img_resize

UPDATE: feature branch now deleted, but commit preserved as reference (proposal: scroll view acts like regular scrolling webpage => no arbitrary resize-to-fit imposed by reading system, just application of authored CSS styles).

I do not think that this is a fully-satisfactory solution though, as many books I tried have image width/height either set via CSS or attributes, and the application of maximum values irrespective of aspect ratio sometimes produces unexpected / undesirable results. Furthermore, some images do not resize when opening the page for the first time, only when resizing the viewport.

In fairness though, the same problem already exists with the columnized paginated view:
https://github.com/readium/readium-shared-js/blob/develop/js/views/reflowable_view.js#L669

...so one could argue that the behaviour should be consistent across all types of reflowable views, and that we should apply the same image resizing algorithm to the scroll view?

I created a test file and verified this bug in the current build of the Chrome Extension. The file is here:

We'll need to add this for svg's as well in your feature branch. It's just a matter of adding 'svg' to the jquery selector we use.
