Review request for Plasma, David Edmundson and Martin Klapetek.


Changes
-------

Reviewboard is broken with 3200x2000 images. It accepts them and makes thumbnails, but trying to view the original images gives 403 error.

I uploaded a cropped version that shows just the top-left part.

Full images before: http://quickgit.kde.org/?p=breeze.git&a=tree&hb=cd4328238&f=wallpapers%2FNext%2Fcontents%2Fimages
Full versions after: http://oserv.org/files/kde/wallpaper-horizon/desktopWallpaper-horizon-1.1-kvermette.splitnoise.svg.out.x4/images/


Description
-------

Atm, 5.4 wallpapers have pixelated lines and blurred noise (the same as https://bugs.kde.org/show_bug.cgi?id=346018 for 5.3).

I re-rendered them using the same script (4x supersample antialiasing and split noise).

Split noise means that the noise pattern is not scaled for the different resolution wallpapers (which looked bad on both too low and too high resolutions), but is post-applied and tiled.

I uploaded the renders and the patch against the 'breeze' repo to http://oserv.org/files/kde/wallpaper-horizon/ 

Also there is an updated version of the script (render.sh), but the only difference from the previous version is that I added some more comments at the top.

When reviewing, everything should be viewed at 1:1 scale.

Testing
-------

Just opened the wallpapers at 1:1 scale and compared them.
Also I put the corresponding resolution version as my current wallpaper =).
