* Various FocusManager related tweaks to limit its usage to devices with a DPad, and prevent initial button highlights in Dialogs on devices where it makes no sense (i.e., those without a DPad. And even on DPad devices, I'm not even sure how we'd go about making one of those pop up anyway, because no Touch ;)!).
* One mysterious fix to text-only Buttons so that the flash_ui highlight always works, and always honors `FrameContainer`'s pill shape. (Before that, an unhighlight on a text button with a callback that didn't repaint anything [say, the find first/find last buttons in the Reader's search bar when you're already on the first/last match] would do a square black highlight, and a white pill-shaped unhighlight (leaving the black corners visible)).
The workaround makes *absolutely* no sense to me (as `self[1] -> self.frame`, AFAICT), but it works, and ensures all highlights/unhighlights are pill-shaped, so at least we're not doing maths for rounded corners for nothing ;).
Adds new options to the Links> submenu, for now only
available and used with CRE documents.
- Allow larger tap area around links
- Ignore external links
- Show footnotes in popup
- Show more links as footnotes
(This last item is mostly for testing and loosening the
footnote detection algorithm, and see how it would behave
with glossary-like links and inter glossary terms links.)
Fix distance computation from gesture position to link by
using segments.
Code for detecting if a link is a footnote is in cre.cpp, and
tweakable a bit with flags in ReaderLink:showAsFoonotePopup().
Footnotes HTML content is displayed by a new FootnoteWidget,
which uses MuPDF for its rendering.
From it, swipe south or tap outside to close, swipe to the left
to follow the original link and jump to the footnote location
in the book.
Also fix tap on highlights after the recent change to use segments
for displaying: use segments also when checking taps.
* Adds a generic HTML widget modeled after the text widget, and HTML dictionary support. HTML dictionaries can have their own CSS (for X.ifo it must be X.css). The base CSS just resets the margin and sets the font.
Note that the widget doesn't handle links, that wasn't needed for the dictionary.
Closes <https://github.com/koreader/koreader/issues/1776>.
* Show tag stripped HTML if the dictionary entry isn't valid HTML
* Simulate the normal <br/> behavior
* Bump base
