From 557fa1f45e413777a31b1bb2db4eee826c3ee486 Mon Sep 17 00:00:00 2001 From: Tao Bao Date: Tue, 7 Feb 2017 12:51:00 -0800 Subject: minui: Move graphics_{adf,drm,fbdev} into classes. This CL defines minui_backend as an interface, and expresses the three backends (adf, drm and fbdev) as subclasses to the interface. Test: 'Run graphics test' on N9, Pixel C and N5X.
