Improve output of multiple screen resolution
To improve output on various monitor with various resolution, the following items are introduced. * Abandon scaling by Weston/IVI-SHELL This is cause of huge memory consumption on AGL CES2018 Demo because all contents are designed and rendered with FullHD resolution. * Add parameter of 'scale' to WM API (getDisplayInfo) WM calculate scale factor from screen resolution from wayland compositor and parameter of layout from WM's configuration, area.db. Bug-AGL: SPEC-1568, SPEC-1569, SPEC-1611 Change-Id: I5eac2da0106228c296550135c5200b2653864fdf Signed-off-by: Tadao Tanikawa <tanikawa.tadao@jp.panasonic.com>
