Add 'usedpiscale' boolean (true by default) to love.window.setMode's settings table and love.conf's t.window table. Add love.window.getNativeDPIScale.

Browse Source 
When usedpiscale=false, love will no longer automatically scale coordinates by the screen's DPI scale factor (so all coordinates will be in pixels), even when highdpi=true. love.window.getDPIScale will return 1, love.graphics.newCanvas will default to a dpi scale of 1 instead of the screen's dpi scale, etc.

love.window.getNativeDPIScale() will return the screen's DPI scale as reported by the OS no matter what usedpiscale is set to.
