That's mainly what I'm interested in, as it'll allow users to simply double-click to open wonderbrush files.
IIRC, it at least tries. But it may be broken. In any case, installing the mime type by the build system will allow to double click WonderBrush files without first running WonderBrush, even if WB did install a correct sniffer rule on first launch.
However, I think there is something broken about all this. Just the presence of the WonderBrush executable, or any other app for that matter, should declare the supported file types to the system and make double clicking work out of the box. At least as soon as the mime sniffer has seen the executable file. That's because apps are also supposed to declare their supported file types in their resources and the mime sniffer is supposed to extract the information. And we definitely run the mime sniffer past all installed apps on first boot.
So either something doesn't work with that, or not all apps declare all supported types the correct way, or the information in the resources is somehow not complete, i.e. lacks sniffer rules.
If we did everything correctly and how this is supposed to work, the only mime types we would need to declare separately in the build system are either types that we have no application for, or those types that are specific types which an app that has generic support doesn't want to mention. Like MediaPlayer shouldn't have to declare sniffer rules for AVIs or MP3s when it just wants to declare support for "video/*" and "audio/*".
