Make logicalDpi consistent in relation to device pixel ratio
In GNOME/Unity XCB, logical DPI is scaled by device pixel ratio, and on
Macs logical DPI is constant but pixel ratio is based on physical DPI,
making logical DPI effectively physical DPI divided by pixel ratio.
This patch ensure the same logic is used for other XCB desktops.
