[PATCH 30/36] expo: Plumb in textlines to a scene
Simon Glass
sjg at chromium.org
Tue Sep 19 20:09:00 CEST 2023
Provide an implementation for textlines in the scene code, so that they
are displayed correctly. Provide a way to have a border around the
textline, with the internal part being the same colour as the
background. This looks more natural.
