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.
The highdpi window flag must be enabled to use the full pixel density of the screen on Mac OS X and iOS. It is not currently supported on Windows and Linux, and on Android it is effectively always enabled.
