Subject: Use Meta.BackgroundActor instances instead of cloning global.background_actor
X-Git-Tag: archive/raspbian/50.5-1+rpi1~1^2~1013^2^2~7865
X-Git-Url: https://dgit.raspbian.org/%22http://www.example.com/cgi/%22/%22http:/www.example.com/cgi/%22?a=commitdiff_plain;h=82ce8fe3ff2316af559e3d62d1858f18c4a91007;p=gnome-shell.git

Use Meta.BackgroundActor instances instead of cloning global.background_actor

Instances of this class share a single CoglTexture behind the scenes which
allows us to show the background with different rendering options without
duplicating the texture data.
