X11-native systray icon

[RealKC]

Context

Currently kcshot uses ksni exclusively to create a systray icon, this only works on systems that have a KDE/freedesktop Status Notifier Item host, which on WMs, means snixembed mostly (at least it does on awesomewm, which is what I use), it'd be nice if this dependency could be dropped.

XEmbed-based solution

This solution would make use of the old (and I imagine deprecated) systray specification, the high level overview of what needs to be done is:

1. Create a window in the systray area using xcb
2. Give ownership of it to gtk
3. Add an image widget and a menu on right click

I, however, have been unable to make this work, my past attempts:

• Attempt 1
• Attempt 2

Alternatives

1. Do nothing, preserve the status quo
2. Make a special systray binary that runs in its own process and uses gtk3+libappindicator. It'd work, but I'm not sure I like this option
