Summary: GDK SCALE leads to wrong resolution in wayland

Description Fabian 2018-04-21 19:54:59 UTC 
Setting up GNOME in HiDPI mode (GDK_SCALE=2) and now launching a sdl2 using game with it's wayland backends leads to a 2x greater resoltion.

So Windows that are rendered for a 1920*1080 resolution will be streched to 3849*2160. While this sounds logical, it isnt. The content is just streched, rendered in 1920*1080.

Basically there is no HIGHDPI support in the Wayland backend at all - it's implemented only in macOS, iOS and Emscripten ones so far.
