This function is not supported in earlier versions.
Gets the DPI scale factor associated with the window.
The pixel density inside the window might be greater (or smaller) than the "size" of the window. For example on a retina screen in Mac OS X with the
highdpi window flag enabled, the window may take up the same physical size as an 800x600 window, but the area inside the window uses 1600x1200 pixels.
love.window.getPixelScale() would return
2.0 in that case.
highdpi window flag must be enabled to use the full pixel density of a Retina screen on Mac OS X and iOS. The flag currently does nothing on Windows and Linux, and on Android it is effectively always enabled.
scale = love.window.getPixelScale( )
