Enable scaling to fit various screen resolutionseel_5.1.0eel_5.0.3eel/5.1.0eel/5.0.35.1.05.0.3eel
Since the AGL HomeScreen of CES2018 assumes that the screen resolution is 1080x1920px, the graphics of it partially corrupted with others. To fix this issue, now the AGL window manager automatically scales size of HomeScreen to fit the resolution of the display. By default, this scaling keeps HomeScreen's original aspect rate (9:16). To ignore it, set the environment variable, 'HMI_SCALING_IGNORE_ASPECT'. (E.g. set it in any file under /etc/afm/unit.env.d/) Bug-AGL: SPEC-1138 Change-Id: Id11a07560fe254712aaab42018bfb4d1d87ad1df Signed-off-by: Tadao Tanikawa <tanikawa.tadao@jp.panasonic.com>
