Adapt to premultiplied alpha usage in Cogl (2.79 KB, patch)
2009-06-11 19:36 UTC, Owen Taylor 		none Details | Review

Description Owen Taylor 2009-06-11 19:36:11 UTC 
Cogl's default blend function has been switched to expect premultiplied
alpha. Change the combine function and the colors we use to
modulate alpha to match.

Pushed this ... I've been testing the equvialent code for a while, (older versions attached to http://bugzilla.openedhand.com/show_bug.cgi?id=1406), am pretty confident, and want to get things working again as soon as possible.
