Adjust image colors for PocketBook color devices to supply
brighter image colors. Make it a config option so we can
adjust it to a sensible default for all devices later.
Also enable HW Dithering for color devices: the dithering
flag allows us to figure out if what is viewed is an
image or text. This way we can enable color rendering
or not based on the dithering flag.
Piggybacking on the touch gesture handlers implied that the gesture
filter (tap and/or swipe) was still applied, which made no sense.
Also, stop the weird Event roundtrip for events we're actually the only
ones to handle, just call the handler ourselves directly.
Fix#9792
It possibly historically never made it out of InkView in the past, but
apparently that's no longer the case and/or every other key behaves the
same way anyway, so it's harmless at worst.
Fix#9791
Adds the ability to re-assign which book a word belongs to
and change the name of an existing book. It can be used as
a way to regroup words and hide/show them by book.
Fix regression introduced by 48eb0231#9651: on re-rerendering, the new pages count didn't reach the Statistics plugin.
So, if you change font size or margins, the stats for the page read since then were badly accounted, until a change of book or restart... I noticed that in Book map, strange nobody else did over the last 2.5 weeks.
This commit adds cross-device sync ability for two plugins: reading statistics and vocabulary builder. It relies on user setting up a Cloud server (DropBox and WebDAV but not FTP though) and designating a path. Behind the curtains sqlite databases are being passed around and updated.
UI-wise, for the statistics plugin, two new menu items Synchronize now and Cloud sync to set it up (might not be the best wording) are added. As for vocabulary builder, a similar Cloud sync button is added to the menu and a shortcut icon button to Synchronize now is pinned at the bottom corner.
CloudStorage new features: WebDAV creating folders and uploading files. And a new widget-like sync server chooser. In the end I decided not to add automatic sync, as the SQL commands part seem a bit much.
This is made easier by the fact that only a single method in a single
widget actually handles Gesture, and that we barely ever overload it.
So, apply a bit of monkey-patching trickery to handle the magic :).
Fix#9695
Tools and humans alike are confused by leaving it empty. It should be inoffensive to resolve the problem this by having an unused singular. Doing anything else would make it so we couldn't have the correct plurals in Slovak, among others.
