Description of problem:
In Fedora 21 we show any valid application in the software center with an application icon of 32x32 or larger. Currently a 32x32 icon has to be padded with 16 pixels of whitespace on all 4 edges, and *also* has to be scaled x2 to match other UI elements on HiDPI screens.
This looks fuzzy, out of alignment and lowers the quality of an otherwise beautiful installing experience. For Fedora 22 we are planning to increase the minimum icon size to 48x48, with recommended installed sizes of 24x24, 48x48, 64x64 and 256x256 (or SVG).
Modern desktop applications typically ship multiple sizes of icons in known locations, and it's very much the minority of packages in Fedora (69 out of 1042) that only ship such small icons.
I'm asking package maintainers to install a larger icon than 32x32 in the Fedora package. Most of the time this will involve just installing a different icon from the tarball, but could also mean contacting upstream and asking them for larger icons and a new tarball release.
If you're asking upstream, please ask for a 256x256 or 64x64 icon, as the latter will probably be the minimum size for F23 and beyond. If you want to fix up F20 and F21 too that would be great, but not expected.
At the end of November I'll change the minimum icon size in the AppStream generator so that applications not fixed will not be shown in the software center. You can of course install this application in F22 with dnf on the command line, but it won't be visible in the software center until they are installed manually.
If you're unclear on what needs to be done in order to be listed in the software center, refer to this https://github.com/hughsie/appstream-glib#what-is-an-application or comment here.
I don't use the software center (and Gnome at all), thanks for reporting this issue. I'll have a look at it next days.
First thoughts: The current v1.1 tarball is almost five years old, so I consider to use a Git snapshot. There we have a png icon with 219x219, somewhat odd, but usable after padding to 256x256. And moreover, we have already an appdata file. So it would be the best way to take the sources from Git instead to bother with the current stable version.

Great, thanks. AppStream metadata is produced and consumed by KDE too, so it's not a GNOME-specific initiative.

In this case perhaps that's best; could you convince upstream to make a new release in the next few months?

Right. If you don't pad it, the appstream builder will try to resize it to something sane (e.g. 128x128) but padding might be good if the logo is designed to have an alpha border.
