Summary:
QSortFilterProxyModel uses std::stable_sort internally which requires that the
comparison function generates a strict weak ordering. Returning true or false
randomly didn't fullfil this requirement causing a crash in some calls to invalidate.
To keep the random order consistent a vector of row indices is used which records
the current random order.
BUG: 413018
FIXED-IN: 5.17.1
Test Plan:
To reproduce the bug use a slideshow in random order with few pictures and a small
time intervall.

Summary:
Allows setting of other sorting orders like alphabetical or last modified date.
To enable this a new ProxyModel is introduced which handles the sorting and
filtering (as indicated by the checkboxes). This is backed by the slideshowModel
whcih previously as only used for the configutation. The lists of slides and unseen
slides are dropped as now the slides that are shown are taken from the model.

Summary:
This allows to exlude single images from the slideshow by unchecking the little checkbox in the top right corner.
Feature or todo?: If a folder is removed I don't touch the unchecked Slides. So the list could get very big but if a formerly removed folder is
added again an excluded image will be excluded again.

- Uncheck some images

Summary:
This shows all the pictures inside the folders added to the Folders list. I also tried to make single pictures excludable via a checkbox on the thumbnail. This is the first time for me programming with QT/QML/Singals-Slots and I tried to use as much existing code as possible. The thumbnail view is the same as for single images and I simply subclassed the listmodel. However even if I tried to do everything like the code for slidePaths it doesn't work correctly. The checking/unchecking of images only applies on restart of plasmashell. Maybe it's a single mistake that is easily spotted by a more experienced programmer otherwise if the thumbnail view is accepted I can also revert all the checkbox stuff.

Wait for m_ready until doing anything. This keeps the slideshow from first showing the default wallpaper,
then a random slideshow image, and then fade to the next slideshow image.

Directly expose "targetSize" as property. The wallpaper is already initialized with
the correct size for some time now but the fact that we had two properties width and height
in there had it still do unneccessary work when it emitted "sizeChanged(2560, 0)" and
then the final "sizeChanged(2560, 1440)" afterwards.
Also, I didn't really see a point in storing the wallpaper size in its config,
it's overwritten by the wallpaper anyway and only used in the wallpaper config dialog
for the aspect ratio. We can just ask the view directly then.

Differential Revision: https://phabricator.kde.org/D4001
Summary:
This new version of the distance function simplifies the
findPreferredImageInPackage method by using the aspect ratio in the
calculation. Now, it won't only search for a wallpaper with the same
aspect ratio, but will also choose one with the closest possible
aspect ratio when a perfect match is not found.
Also, I separated the method that chooses the preferred image
to not use KPackage in order to use it from a test application
that tests the distance algorithm with all possible resolutions.
Test application that tests the Image::findPreferredImage method
The test initializes a list of available wallpaper image sizes,
then a list of screen resolutions, and then executes
Image::findPreferredImage to find out which is the preferred image
in each case.
Test Plan:
I tested with different screen resolutions on a virtual machine with
openSUSE Leap 42.2 RC1 and also included a commit that adds a test
application (not built by default) that tests all possible resolutions.

Summary:
Removes preferred definition so a new wallpaper is selected.
Also, just in case, check for division by 0.
When the screen resolution changes, a new wallpaper has to be chosen
but this is not happening unless we remove the preferred definition.
This depends on https://git.reviewboard.kde.org/r/129118/ to be accepted.
Test Plan:
I ran plasmashell with the default opensuse wallpaper (a green bulb)
while changing the screen resolution between 1024x768 and 1280x720.
With this and the kpackage patch above, a different background image is
selected correctly with the correct aspect ratio.

Summary:
The default wallpaper method is to scale the wallpaper, and the previous
algorithm in plasma choosed the wallpaper with closest area to the screen
area (w*h) giving a bit of preference to downscaling over upscaling.
The result was that in widescreens like 1280x720, a 1280x1024 wallpaper
was preferred to be scaled down, instead of scaling down the also
available 1920x1080 wallpaper, which had the same aspect ratio and so,
was not distorted.
This patch changes the Image::findPreferedImageInPackage method to do the
same closest-area algorithm first on wallpapers with the same
aspect ratio and if no wallpaper with same aspect ratio is found, then
fallback to the previous algorithm. Note I added some variables so both
happen in the same loop and we don't have to iterate twice
over the wallpapers.
This fixes https://bugzilla.opensuse.org/show_bug.cgi?id=990257
Test Plan:
Make sure the wallpaper mode is in Scale. Choose a wallpaper with
1920x1080 and 1280x1024 resolutions which shows a perfect circle,
a recognizable object or a face. Then change the screen resolution to
1280x720. The wallpaper should appear with correct aspect ratio.

BackgroundFinder::suffixes(), despite its name, actually returns a list
of glob patterns. The extension of the image file is checked against
this list to ensure that it is supported, which needs to take
account of that. Do the check in a new function
BackgroundFinder::isAcceptableSuffix(const QString &suffix).

Update the targetSize when it changes to ensure we update the image when
resolution changes. Also, since the view has an initial size of 1024x768, it would
just load that image and never use the full resolution leaving you with an ugly
blurry image. Additionally, don't bother looking up the image until everything has
settled, potentially improving startup performance slightly by saving a bit of IO.
REVIEW: 124311
* when dropped w/out a url scheme, check if it is an abs path
* set the preferred file in the package itself for single files
* don't try and find a best fit in the wallpaper plugin if the package
has already set a prefrred image
this will allow it to be shared by other plugins out there. it does mean
sacrificing the generic "find best paper size" functionality which was
tightly bound to the image wallpaper (in plasma4, this was Plasma::Wallpaper,
so acceptable). Finding the best image is now left up to the plugin,
though I imagine that other plugins will want this eventually as well
and it will find its way into a library somewhere or else just be
copy-and-pasted a lot.
