Now that the client can listen on sockets (#2406), we can enhance the packet handlers to make this feature more useful:

• support control commands
• more detailed information on windows and their state

See also #2742, #2743.

Done:

• r26888 add window information, r26889 add backing details - this was made easier by r26322, which already provided some info methods for windows
• r26890 control commands

---

Examples with a server (any), and a client started using:

xpra attach --bind-tcp=0.0.0.0:10001

xpra info tcp://127.0.0.1:10001 | grep backing.type

xpra control tcp://127.0.0.1:10001 debug enable x11

xpra control tcp://127.0.0.1:10001 show_session_info

xpra control tcp://127.0.0.1:10001 show_bug_report

etc..
