Subject: expo: Allow highlighting other scene-object types
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-logo.png?a=commitdiff_plain;h=d88edd2bda2150b253fac702dd26ec4c01ccf988;p=u-boot.git

expo: Allow highlighting other scene-object types

So far only menus can be highlighted. With the coming addition of
text lines we need to be able to highlight other objects. Add a function
to determine whether an object can be highlighted.
