Implement a cache pixmap for avatars
Review Request #102050 - Created July 22, 2011 and discarded
At the moment, each time an avatar is requested, a new pixmap from the image file is created. This is of course more than evil, and this patch aims to fix that. PixmapCache is a proxy to QPixmapCache for handling avatars' pixmaps efficiently. If this patch gets in, from now on every avatar consumer (tooltips, list view, etc) should get his avatar pixmaps through the cache. Of course, in the future, this will be extended to support the most common and most unefficiently handled pixmaps in our code.
Apparently everything still works
