Long-pressing on the "edit" buttons switches between "word" and "char" modes of the following single taps.
Long-pressing always moves the boundary by char.
Initially, when you open the dictionary widget from the reader, FocusManager will function as usual. On Kindle 4 or devices with a keyboard, I have assigned the shortcuts <kbd>screenkb</kbd> + <kbd>up</kbd>/<kbd>down</kbd> or <kbd>shift</kbd> + <kbd>up</kbd>/<kbd>down</kbd> to initiate text selection (as a remainder, on kindle text selection in reader is initiated with <kbd>up</kbd>/<kbd>down</kbd> so it is fairly similar). At this point, FocusManager is disabled, allowing the cursor keys (and press) to control the now-visible crosshairs. Pressing <kbd>back</kbd> should stop text selection and restore FocusManager’s control of the widget.
* Use a dedicated cache hash for partial tiles from panel-zoom
* Never dump them to disk, as it confuses DocCache's crappy heuristics that rewinds the cache to skip over the hinted page to try to dump the on-screen page to disk.
* Apply the zoom factor in the exact same way as any other page rect (i.e., floor coordinates, ceil dimensions), and make sure said rect is actually a Geom so it doesn't break the cache hash, which relies on Geom's custom tostring method for rects. Said scaling method *also* belongs to the Geom class anyway.
* Handle such pre-scaled rects properly in renderPage, so as not to apply the zoom factor to the full page, which would attempt to create a gigantic buffer.
* And now that the rect is rendered properly in an appropriately-sized buffer, use the rendered tile as-is, no need to blit it to another (potentially way too large because of the above issue) blank BB.
* The zoom factor is now computed for a scale to best-fit (honoring `imageviewer_rotate_auto_for_best_fit`), ensuring the best efficiency (ImageViewer won't have to re-scale).
* Cache: Reduce the maximum item size to 50% of the cache, instead of 75%.
* Warn about the legacy ReaderRotation module, as it turned out to be horribly broken. The whole machinery (which is spread over *a lot* of various codepaths) is left as-is, peppered with notes & fixmes hinting at the problem. Thankfully, that's not how we actually handle rotation, so it was probably hardly ever used (which possibly explains why nobody ever noticed it breaking, and that nugget possibly dates back to the inception of the kpv -> ko refactor!).

Getting text from xpointers to get the current selected
word context would have crengine unhighlight that word.
Allow to get it selected again when done getting context.
* UIManager: Let the fb backend deal with Kaleido wfm promotion. This fixes a number of quirks that poisoned the refresh queue with spurious full-screen refreshes. See https://github.com/koreader/koreader-base/pull/1865 for more details.
* This also means we now disable Kaleido waveform modes when color rendering is disabled (remember to trash your thumbnail cache if you don't want to mix color w/ grayscale thumbnails, though).
* UIManager: Merge refreshes that share an edge, because that was driving me nuts (and would have most likely been merged by the kernel anyway). A perfect test-case is the FM, which trips two separate refreshes because of its title bar.
* ReaderFlipping: Use sensible dimensions, so that we only refresh the icon's region.
* ReaderBookmark: Only refresh the dogear instead of the whole page when toggling bookmarks.
* NetworkSetting: Make it a real boy, so it consistently refreshes properly on dismiss instead of relying on UIManager saving the day.
* Kobo: Aggressively prevent *both* suspend & standby while MTK devices are plugged-in, as both will horribly implode the kernel (we previously only prevent standby while charging).
* Kobo: Switch to 8bpp on B&W MTK devices (or when color rendering is disabled on Kaleido panels).
as first discussed here #11908. This PR brings the book map to non-touch devices that useDPadAsActionKeys().
Book map can be accessed from the menu or by using the following shortcut: ScreenKB + Down or Shift + Down depending on whether you use a K4 device or a kindle with keyboard respectively.
Inside the book map, a user can toggle the hamburger menu by pressing the Menu key and make any adjustment from there. ScreenKB (or Shift) + Up/Down allows it to scroll and Page turn buttons to move by whole full page turns. Back key allows user to exit the map.
1. Non-Kindle-specific `hasFiveWay` behavior is changed to `hasDPad and useDPadAsActionKeys`. For now they remain Kindle-specific in practice, unless one sets `useDPadAsActionKeys = yes` in a user patch.
2. With that disambiguation out of the way, `hasFiveWay` itself is further disambiguated into `hasScreenKB` and `hasSymKey`, as per the actual property being used, rather than something that tends to correlate with it. (It needn't be Kindle-specific per se, but non-Kindle devices have equivalent shortcuts with for example `Shift`.)
Running the emulator with `DISABLE_TOUCH=1` will set `hasSymKey = yes`, which can be tested with right shift.
Closes#11887.
