Fix DPI with 0 width/hight reported by xorg (#544)

Browse source 
* Fix DPI with 0 width/hight reported by xorg

* Add `WINIT_HIDPI_FACTOR` env variable

It is now possible to override the DPI factor using the
`WINIT_HIDPI_FACTOR` environment variable on X11.

The changelog also has been updated to introduce all current changes
made.

* Add documentation for the environment variable

* Fix nitpicks

* Learning the alphabet

* Panic with error message if DPI env var is <= 0
