* Enable HW dithering on supported devices (Clara HD, Forma; Oasis 2, PW4)
* FileManager and co. (where appropriate, i.e., when covers are shown)
* Book Status
* Reader, where appropriate:
* CRe: on pages whith image content (for over 7.5% of the screen area, should hopefully leave stuff like bullet points or small scene breaks alone).
* Other engines: on user-request (in the gear tab of the bottom menu), via the new "Dithering" knob (will only appear on supported devices).
* ScreenSaver
* ImageViewer
* Minimize repaints when flash_ui is enabled (by, almost everywhere, only repainting the flashing element, and not the toplevel window which hosts it).
(The first pass of this involved fixing a few Button instances whose show_parent was wrong, in particular, chevrons in the FM & TopMenu).
* Hunted down a few redundant repaints (unneeded setDirty("all") calls),
either by switching the widget to nil when only a refresh was needed, and not a repaint,
or by passing the appropritate widget to setDirty.
(Note to self: Enable *verbose* debugging to catch broken setDirty calls via its post guard).
There were also a few instances of 'em right behind a widget close.
* Don't repaint the underlying widget when initially showing TopMenu & ConfigDialog.
We unfortunately do need to do it when switching tabs, because of their variable heights.
* On Kobo, disabled the extra and completely useless full refresh before suspend/reboot/poweroff, as well as on resume. No more double refreshes!
* Fix another debug guard in Kobo sysfs_light
* Switch ImageWidget & ImageViewer mostly to "ui" updates, which will be better suited to image content pretty much everywhere, REAGL or not.
PS: (Almost 💯 commits! :D)
- css tweaks: use correct CSS "hyphens:" instead of "hyphenate:"
- screenshoter: more logical order of lines (no change in what it does)
- textviewer: make diagonal swipe really trigger a full refresh
- textwidget: more adequate text length to help with centering
- toggleswitch: fix sizing & centering with correct calculations
(this reduces a bit the size of switches, and may cause a new
truncation in some translations)
* Switch all initial highlights to "fast" update
i.e., everything that does an invert
Plus a few other things that refresh small UI elements onTap
Re #3130
* Tweak refreshtype for a number of widgets:
* Fix iconbutton dimen
* Make touchmenu flash on close & initial menu popup. Full-screen on close.
* Use flashing updates when opening/closing dictionary popup. Full-screen on close.
* Switch FileManager to partial.
It's mostly text, and we want flash promotion there.
* Make configdialog & menu flash on exit
* Make FLWidget flash on close
* virtualkeyboard: flash on layout change & popup.
* Potentially not that great workaround to ensure we actually see the
highlights in the FM's chevrons
* Flash when closing BookStatus Widget
* Optimize away a quirk of the dual "fast" update in touchmenu
* Promote updates to flashing slightly more agressively.
* Document what each refreshtype actually does.
With a few guidelines on their optimal usecases.
* Switch remaining scheduleIn(0.0) to nextTick()
* Tighter scheduling timers
Shaving a hundred ms off UI callbacks...
* Cache FFI C Library namespace
* Ask MuPDF to convert pixmaps to BGR on Kobo
Fix#3949
* Mention koxtoolchain in the README
re #3972
* Kindle: Handle *all* fonts via EXT_FONT_DIR instead of bind mounts insanity
* Make black flashes in UI elements user-configurable
(All or nothing).
* Jot down some random KOA2 sysfs path
This makes button heights similar in all uses of ButtonTable.
It depended on how the ButtonTable was used in each widget
(previously, first and last row may have different sizes than
the others).
buttontable.lua: more even buttons height whether zero_sep or not
framecontainer.lua: added padding_top/bottom/left/right (similar to
what was done for iconbutton)
The following widgets have been adapted for this, with some
additional fixes:
buttondialog.lua
buttondialogtitle.lua: wider title with adequate padding
confirmbox.lua + multiconfirmbox.lua: dismissable via tap outside
inputdialog.lua + multiinputdialog.lua: more even vertical padding between elements
imageviewer.lua
textviewer.lua
datewidget.lua
timewidget.lua
Additionaly: frontlightwidget.lua: fixed width of progress bar that
was exceeding window width since the Size scaling adjustements
