Cairo-dock doesn't check for missing composite manager when starting next time :(

[Mantas Kriaučiūnas]

Cairo-dock 3.1 displays a nice tip about missing composite manager, but only on first start:
"To remove the black rectangle around the dock, you need to activate a composite manager."
"Do you want to activate it now?" (see attached screenshot)

This is enough if user uses only one desktop environment/computer, but I miss this tip when user uses the same Home folder with different desktop environments/computers.

I'm wanna create universal LiveUSB (with persistence) with mixed Desktop environment: GNOME3 shell with Cairo-Dock and fallback to GNOME3 Classic with Metacity and Cairo-Dock.

It would be very nice if Cairo-dock would check for missing compozite manager when starting every time (please, at least make a setting for this option).

Thanks for creating nice free software,

IIUC:
the first time you start with Compiz, composite is ON and checked.
then you start with Metacity and composite is not tested.

OK for testing it every time.

This bug should be fixed now (on BZR), thanks to fabounet ;)

@Mantas: thank you for using Cairo-Dock on your distribution and feel free to report any bugs or ideas ;)
BTW, if you're using Cairo-Dock with Metacity, it can be interesting to use the new '-W' option (cairo-dock -W) in order to work around some bugs in Metacity Window-Manager (invisible dialogs or sub-docks)
