Getting mouse position in window not working with the old fill-window example

[SwagDeNoli]

Noticed while using the fill-window renderer mouse position is incorrect
Modified example code: https://gist.github.com/SwagDeNoli/8724152fa782f11d8907b96d511816a8
The pixels/winit mouse position code is off (possibly due to the custom renderer?)

Possibly caused by the custom renderer. I'd have to revisit that PR to be sure, but thank you for reporting the issue!

I'm looking forward to that. For the time being I'll start using the default renderer + update to the more recent version, as I can workaround not using it for the moment.
