GetContentScaleFactor() returns 1.0 under Linux even if scaling is set to 200%

[DarkFenX]

Operating system: Debian Testing, affects X11 installation - cannot test on Wayland
wxPython version & source: 4.0.6+dfsg-1 from Debian repo
Python version & source: python 3.7 from debian repo

Description of the problem:
Content scaling is returned as 1 despite actually being 2, which leads to inability to use hi-res assets within the app.

import wx


class MainFrame(wx.Frame):

    def __init__(self):
        wx.Frame.__init__(self, None, wx.ID_ANY, 'test')
        self.Maximize()
        self.Show()
        print(wx.GetApp().GetTopWindow().GetContentScaleFactor())


app = wx.App(False)
mf = MainFrame()
app.MainLoop()

Looking through the docs, i suppose it's something which is handled by FromDIP in 3.10? https://wxpython.org/Phoenix/docs/html/wx.Window.html#wx.Window.FromDIP

The GTK3 implementation of GetContentScaleFactor in 3.1 is doing the right thing:

Yep. wxWidgets issue. We're looking at trying to backport some of the HiDPI fixes to 3.0 though.

FYI returns 2.0 in 4.0.7.
