Review request for Plasma.


Repository: plasma-framework


Description
-------

LayoutChanged causes QML to destroy all delegates and re-create them. Since the number of days doesn't change but only the numbers, we can just call dataChanged on all roles.

Furthermore, when agenda-related data changes, only the containsEventItems role might have changed, so only emit a change for it.

Testing
-------

Scrolling through the calendar still properly updates the day numbers, the selected day and "today" marker as well as the "has event items" badge.

Scrolling quickly through the calendar is now pretty fast and smooth but the initial lag when opening the calendar for the first time is still there.


Thanks,

Kai Uwe Broulik
