* ImageViewer: Minor code cleanups
* GestureDetector: Fix the `distance` field of `two_finger_pan` & `two_finger_swipe` gestures so that it's no longer the double of the actual distance traveled. Get rid of existing workarounds throughout the codebase that had to deal with this quirk.
It is a bit cleaner to do all of the necessary looping over lists of
Geoms within a straight-forward Geom.boundingBox function rather than
looping over :combine every time (or reimplementing :combine in some
cases). Geom:combine can be trivially reimplemented in terms of
Geom.boundingBox as well.

* Geom:transformByScale:
* Apply the right scaling factor to the y axis
* Round in a more sensible fashion (àla fz_round_rect, since we pretty much exclusively use it in a similar fashion).
* Bump base (https://github.com/koreader/koreader-base/pull/1407)
We've managed to trip a few of those on dimen fields post-init but
pre-paintTo in a few weird coner-cases, a point at which dimen is often
nil.
ConfigDialog: Deal with that very thing in update()
Fix#7656
* Simplify flash_ui handling (by handling the unhighlight pre-callback, c.f., #7262 for more details).
* UIManager: Handle translucent window-level widgets (and those wrapped in a translucent MovableContainer) properly in setDirty directly, making sure what's *underneath* them gets repainted to avoid alpha layering glitches. (This was previously handled via localized hacks).
* Update UIManager's documentation, and format it properly for ldoc parsing, making the HTML docs more useful.
* ReaderView: Reinitialize the various page areas when opening a new document, to prevent poisoning from the previous document.
* Event: Handle nils in an event's arguments.
* CheckButton/RadioButton: Switch to simple inversion to handle highlighting
* CheckButton: Make the highlight span the inner frame's width, instead of just the text's width, if possible.
* AlphaContainer: Fix & simplify, given the UIManager alpha handling.
* MovableContainer: When translucent, cache the canvas bb used for composition.
* Avoid spurious refreshes in a few widgets using various dummy *TextWidgets in order to first compute a text height.
* KeyValuePage: Avoid floats in size computations.
* In ReaderPaging, the panning step pre-PanningUpdate can be wildly overshot near page edges, so, use the corrected value instead by recomputing it after the panning has been effectively computed by ReaderView.
This fixes slight inaccuracies, as well as glaring mistakes when going backwards, or when near page edges.
This is in line with how ReaderRolling computes the value, which I only realized later because I'm an idiot.
* Minor cleanups around the handling of the dim_area Geom object in general.
* Fix the "Arrow" page overlap mode to be painted in the right coordinates when going backward. Issue might not have been terribly clear because of the previous issue ;).
* Center the arrow's point, while we're here.
* Don't use AlphaContainer to make it translucent, because AlphaContainer is horribly broken, and has weird quirks and behavior that make no sense to me unless some very specific and unlikely constraints are met, and they definitely aren't here.
This fixes the arrow copying an arrow-sized square of the original page the book was opened on on the top-left corner of *every* page with an arrow. (lol).
* Do real proper alpha-blending via Icon/ImageWidget from the original icon, instead of faking it via addBlitFrom, in order to avoid the dimming *around* the triangle's shape.
This commit standardizes the various todos around the code a bit in a manner recognized by LDoc.
Besides drawing more attention by being displayed in the developer docs, they're also extractable with LDoc on the command line:
```sh
ldoc --tags todo,fixme *.lua
```
However, whether that particular usage offers any advantage over other search tools is questionable at best.
* and some random beautification
Touch zone decouples screen size from gesture event registration.
The win here is each individual widget does not need to update
gesture range on screen rotate/resize anymore.
Another advantage is we now have a centralized ordered array to handle
all registered touch event listeners, makes it much easier to resolve
gesture range conflicts between multiple widgets.
This patch also includes the following changes:
* migrate readerpaging to use readerui's touch zone
* migrate readerfooter to use readerui's touch zone
* move inverse read direction setting to touch menu's setting tab
* moved kobolight widget from readerview into readerui
* various dead code cleanups and comments
The #1011 bug is caused by the `contains` check of link box with
visible area. When the link is at the very right (left?) of
the page, enlarged link box often exceeds the page bound rendering
the mentioned `contains` check failed. This patch uses an `intersectWith`
test to check if the link is in current page.
In regional zoom mode double tap will zoom to the tapped
region(paragraph or column, etc., detected optically via libk2pdfopt).
As the first demo, this feature is only turned on in flipping mode by
tapping the top-left corner of the screen. Eventually we may incorporate
this feature in "free" zoom mode.
and there is no need to OCR word if we can extract text from
original page in reflowing mode thanks to the rect maps between
normal page and reflowed page.
* add notIntersectWith method for Geom
* add math.roundAwayFromZero in geometry.lua
* Readerview:recalculate now signals ViewRecalculate event.
For now, this event is only usefull for ReaderPaging
a bit of cleanup, switched width/height combo over to use
Geom() objects, moved framebuffer handling to Screen object,
callback syntax sanitizing, lots of small changes
