Subject: [PATCH 1/3] info-overview: add build option to control distributor
 logo

Currently, we display a 256x256 version of the OS icon from
/etc/os-release. This is too big for my taste, and it's also not
sufficient for distros that want to display a logo that is not an icon.
For instance, because we no longer display the operating system name
immediately beneath the logo, it may be desirable to use a logo variant
that includes text. This patch adds a meson build option that
distributions can use to override the logo.

Because the logo might include text, distributions may want to vary the
logo used in dark mode. A subsequent commit will add a second option for
this.

Subject: [PATCH 2/3] info-overview: add build option to specify a dark mode
 logo variant

Let's allow distributions to specify a different logo to use when using
a dark GTK theme. This is best-effort only since it relies on the
convention that dark themes must end with "dark" and therefore will fail
for a theme named "midnight" or anything that doesn't match convention.

Subject: [PATCH 3/3] info-overview: reduce size of logo when using icon from
 /etc/os-release

When using the icon from /etc/os-release, display it as 128x128 rather
than 256x256. In distributions that don't ship a 128x128, such as
Fedora, this results in the 256x256 icon being scaled down to a
reasonable size. 256x256 is so large here as to be clearly undesirable.
128x128 is also the size that Ubuntu uses in its downstream patch. Might
as well reduce the need for patching as far as possible, even though
Fedora doesn't plan to use this codepath.
