Support in the actual installer will follow in another commit.

It only worked half of the time in LMDE 3, it doesn't work at all in LMDE 4...
rely on console instead.

If the height of the installer is slightly too tall it creates a gap between
the slideshow and the footer and breaks the visual effect. This commit fixes
that by expanding the eventbox of the footer.

ubiquity).

of letting QT5 do it itself.

On single-monitor machines, the keyboard layout was fine, but it
seems that QT determines scale based on the largest monitor (or at
least that's the issue that's manifesting here).  So if you have
one normal monitor, one 4k monitor, even if you're not in hidpi mode,
the keyboard layout is rendered twice as large (forcing the window
to be twice as wide also).

Instead, don't enable qt5 hidpi unless gtk says so, and pass this
along to the script.

so when the label is shown, it doesn't resize the scroll boxes.

Even though we're simply creating a png to be loaded after, the
characters on the keys would end up overlapping.

Otherwise we end up with 3 or 4 useless memtest entries in grub.cfg.
Memtest can be handy in a live ISO, but not post-install every time
you boot your computer.

grub is extremely slow to install/update when /run isn't available and eventually
times out on querying udev.

We'll add this as an option in the UI in a future commit.

Also, use /run/live/medium (this seems to work everywhere,
whereas the previous path depended on how the ISO was mounted..
it worked on real HW but not in VBox during the latest tests).

Pretty useless as it is
If we ever need to bring back configuration we'll do
so using gsettings.

Otherwise it pushes the size of the window.

Draw lines also and enable search.

Don't show it by default to everybody in the UI.
