there's already a request with this name as part of the interface. even if this
happens to work, please use a different name to avoid confusion. pin_trusted?

[hirono, 2016/08/25 03:30:12]

Yes, I was confused with the name in <description summary="">. Done

Could you use snake_case_name ?

[reveman, 2016/08/24 18:47:47]

this should be a short sentence that describes the request

[hirono, 2016/08/25 03:30:12]

Done.

[hirono, 2016/08/25 03:30:12]

Done.

Oops, I was also confused. Sorry for mis-leading, hirono-san, and thank you for
pointing this out, David.

+	Request that surface is pinned.
+
+	This is only a request that the window should be pinned.
+	The compositor may choose to ignore this request. The client should
+	listen to set_pinned events to determine if the window was
+	pinned or not. If trusted flag is non-zero, the app can prevent users
+        from exiting the pinned mode.
