[vlc-devel] [PATCH 3/3] Qt: Set proper vout size on hidpi setups.

It's ratio between virtual an physical pixels. Since Qt>=5.6 use it's
own coordinate system, so devicePixelRatio() is only way to roughly
estimate how much real pixels do you have.
It seems odd because there should be both Qt->VLC and VLC->Qt
conversion. This patch offers only Qt->VLC way, i.e setting vout size
in response to user actions. I'm not quite sure from where VLC sizes
come, but, I guess, it should be somewhere inside of
modules/gui/qt/qt.cpp. Fix me if I am wrong, will update the patch.
Idk if there is a real problem when 1:1 is actually N:1 on hidpi.
Exact 1:1 of 1080p video on hidpi screen will look smaller that 720p
on regular one.
Would like to hear your input on problems stated above.
