Since-Version info with ECM macros?

[Friedrich W. H. Kossebau]

Hi,

I am about to use ecm_add_app_icon, but cannot see which mininmal version of 
ECM needs to be required to expect this macro to exist.

At least at
	http://api.kde.org/ecm/module/ECMAddAppIcon.html
there is no hint visible to me. Well, also not in the macro sources itself.

Where would I need to look for that info? Besides git history?

Or is "since-version" tagging something that still needs to be adapted for ECM 
documentation? :) If so, any proposals how to do that best? Would do the dull 
work and prepare a patch.

Cheers
Friedrich
