Subject: expo: Allow rendering the background of any object
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=94598d5b0ab1739279a1f864dc88a8ed3140d7c9;p=u-boot.git

expo: Allow rendering the background of any object

So far only menus have a background. When other object types are
rendered, they may have a background too. Make this code more generic
so it will be usable by new object types.
