+Subject: screen: Increase typical alt-tab icon size to 96
+
+Now we removed thumbnailing in the alt-tab switcher, the switcher is
+more difficult to use with its small icons.
+
+We switch to mutter-like higher resolution icons to be able to distinct
+them better (the new size is about the same order as the thumbnails),
+as more and more applications are providing high-res icons.
+
+This patch is ported from mutter, cf

+Subject: screen: Remove alt-tab thumbnails
+
+gdk_pixbuf_scale_simple generates very nice thumbnails at the expense of
+a very slow rendering. So slow that the alt-tab popup is not usable: it
+needs 3.6 seconds to downscale 30 windows of dimension 1600x900 on an
+fairly recent computer.
+
+We remove the thumbnailing to makes alt-tab blazing fast again in the
+composited mode.
