If the device has natural light support (currently only KA1), use the
sysfs interface instead of the ioctl-based one. It might also be
usable on other Kobo devices for setting brightness without natural
light, but since I cannot test this, this is currently restricted to
the KA1.
By default, the ioctl interface is used for accessing the
frontlight. However, the ioctl interface has two problems: the overall
brightness seems to be lower (issue #2321), and it does not support
the natural light support from the Kobo Aura One (issue #2285). This
interface is the first step to fix both these issues.
From observing Nickel's behavior, it appears the white/green/red
intensities are roughly linear dependent on the 4th root of brightness
and warmth values. This leads to a very quick increase of the
intensities for lower brightness/warmth values, which then saturate
for larger ones. The values for gain/offset were determined by a
simple linear regression, but the plan is to create a widget so that
users may adapt these values to their liking.
First item would be underlined if the device is both Touch and Keys
capable (emulator, android, pocketboot...), which is not really
pretty. Delay that till Keys for focusing are really used.
Fix various inconsitencies: some occurences not highlighted
on displayed page; different occurences highlighted on same
page wheter we went there searching backward or forward; pages
with occurences simply just skipped when searching in one
direction, and not in the other...
To avoid edge cases, crengine will now give back results on up
to 3 pages, that we need to filter.
Bump base and crengine
Also fix some bad filename and extension in epub's OEBPS/content.opf,
Store image files (jpg, png, gif) uncompressed in the .epub as they
don't need compression.
crengine may now give us multiple authors (if multiple <dc:creator>
in epub metadata) separated by \n.
Deal with that where needed.
Limit the number of authors displayed in coverbrowser views.
Bumped base/crengine: multiple <dc:creator> + fix mobi images order
Bumped base: util.runInSubProcess(): give child its own process group
When no manually added specific 'poweroff' or 'reboot' screensaver
settings, use the suspend/sleep settings set via menu with an added
overlay message in top right corner.
Generalized some settings: "White background behind message and images"
and "Stretch covers and images to fit screen", and move "Exclude this
book's cover from screensaver" up a level (and remove this menu item
added by ReaderMenu when closing document).
Don't use memory cache with rendered screensaver images.
ImageWidget: fix wrong behaviour (stretch) when 'file', 'width',
'height' and 'scale_factor' provided: now, keep aspect ratio.
ImageWidget: increase file image mem cache (mostly used for icons)
from 2 to 5MB to be ready for devices with very high DPI.
(each one at top right of each page)
Such images can be loaded dynamically when the display of a page requires it.
Allow alternating between the image and its title with Tap on it.
Allow for viewing this image zoomed in ImageViewer with Hold on it.
DictQuickLookup: add generic support for result.images, that
could optionally be provided in Wikipedia lookup results.
New TrapWidget: invisible full screen widget for catching UI events. Can
optionally display a text message at bottom left of screen (ie: "Loading..."),
used by default by Trapper:dismissable functions when no widget provided.
Added Trapper:dismissableRunInSubprocess() to run a lua function in
a sub-process, allowing it to be dismissed, and returns its return
value(s).
Configure number of items per page (from 6 to 24) - default is 14
Allow filenames to wrap so that we can see the full name
