"partial" refresh causes a full (without black flash) refresh on
Kindle (which uses REAGL mode for partial refresh). This causes a
full redraw of widgets, which is a bit distracting with some of them:
- dictquicklookup: when showing next definition
- infomessage: when displaying a new one (Wikipedia Save as epub)
Also fix bottom menu, that even when closed, would still register
bottom area as dirty: this would cause top menu navigation to
cause a full partial refresh, only noticable on Kindle.
* Fix crash with keyboard navigation of onHold buttontables
Would crash when encountering a separator or when the number
of buttons in a row changes.
* Reset previous selected item on new buttontable
This gives the page position to these modules even in scroll mode.
Also, in readerrolling: don't query battery/charging status
when crengine does not need it (used only when it shows its top
progress bar).
394be8a (#2855) and 2b3b310 (#3183) introduced side effects (scroll mode
crashing and TOC being reset and rebuild). This reverts parts of them
not yet reverted.
Avoid unnecessary work in ReaderView:onSetViewMode() and
ReaderRolling:updatePos() that would result in TOC being reset
and rebuilt (which can take time on books with huge TOC) during
reader setup.
Technically 4.7 is probably fine for all but debugging symbols, for which a simple version check and workaround could be added. However, since all of the CI tests run 4.8 there is no regression prevention and it would be more future maintenance trouble than it's worth.
* Allow for colored rendering
Available with all engines (CRE, PDF, Images).
Needs to manually add setting: "color_rendering" = true
* Disable color for djvudocument
* Use Screen:isColorEnabled()
* Bump base
We previously disabled cache, but that may cause excessive
memory usage with big books. We now use a temporary
cache directory, that we clean when no more needed.
For years they've been smaller on higher DPI devices and likely very few people realized it was technically a bug. These values round up on lower DPI and smaller screen devices.

Closes: #3236 and #3235
Details:
> Also, when looking in days, we see info how many hours we read. It would be great if we could tap a day, it opens info on book(s) we read that day with info pertaining to that day, and if we tap on book, we receive book info for that book.
> Statistics plugin is really great, I started to look in my reading statistics now much more, but all the time I can go only in one way. And I need to exit at lowest level of info. It would be great if I can use statistics plugin like part of menu, to go up and down within statistics data and exit at my wish, not when I have to.
Also added:
* new statistics book by week
* new statistics book by month
* last year by week now we can see days in selected week
* Cache scaled images with scale_for_dpi
* Don't update original self.scale_for_dpi
A same ImageWidget object can be free()'d and re-render()ed,
and we would then lose scale_for_dpi on next renderings
