when u switch songs with popup the album art flickered on/off a few
times because mnpris props updated multilpe times. this ignores new
art url changes if they are the same file/url to avoid flickers.
now music-control can automatically find any mpris provider if its in
a glob domain like org.mpris.MediaPlayer2.* or web browsers like
org.mpris.MediaPlayer2.chromium.* and org.mpris.MediaPlayer2.firefox.*
... as well as the explicit list it has still. if it doesnt have a
provider it polls every 5 sec to look for one.
* added a number of new e_comp functions and macros
* options for disabling effects on objects: this option does not currently have any effect
* all modules which used gadcon popups have been adjusted
* all modules which used input windows to detect close events for gadcon popups have been adjusted to use new popup autoclose functionality
* shelves are now always drawn on the compositor canvas, meaning objects will never get clipped by the shelf (ticket #1810)
* shelves no longer have an event object
