Subject: background: Rename Background 'changed' signal to 'bg-changed'
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~781^2^2~534
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=c7e0c7eb792fcd665adb9901a1eab1fd6a5bd12d;p=gnome-shell.git

background: Rename Background 'changed' signal to 'bg-changed'

Meta.Background has already a 'changed' signal and not to confuse the source
signal with the wrapper one, rename the wrapper class signal into 'bg-changed'.

This will be relevant when we'll inherit from Meta.Background, as signal
emissions from the base class could interfere with the wanted derived class
behavior and with the the grouping of successive changes into a single ::change
emission.
