add multi-resolution icons to AppImage #181

2 / 2 tasks completed

All tasks have been completed

Task	Status
I created the `usr` directory to include the additional files, like the icons at `usr/share/icons/hicolor/xx/apps/osu!.png`	Incomplete
Copied over the existing icons from the flathub repo which already included the different sizes.	Incomplete
Moved the root `osu!.png` in the appdir into the 1024x1024 directory	Incomplete
This `usr` directory could also be used to include any additional files in the future, such as mime type definitions.	Incomplete
I did not include the root icon right now, hoping that perhaps that could be done as a copy action from code, to save some repo size, or do you want me to just copy it in for simplicity?	Completed
The next concern to address is in the `LinuxBuilder.cs` where files in the appdir are copied into the staging directory, there's a loop to copy all files but that probably does not handle directories if I'm right, so we'd need a recursive copy option now.	Completed
on my machine `$XDG_DATA_DIRS` did not contain `/home/dachb/.local/share`, which may be a distro issue and which I fixed I guess	Incomplete
