If we build with older GTK+, the build fails:

Presumably the problem here is Ubuntu Xenial 16.04 which
only has 3.18.9 ?

Indeed:

  $ lsb_release -a
  No LSB modules are available.
  Distributor ID: Ubuntu
  Description:    Ubuntu 16.04.5 LTS
  Release:        16.04
  Codename:       xenial

  $ pkg-config --modversion gtk+-3.0
  3.18.9

We should put in a sanity check for this against our min version

  #define  GDK_VERSION_MIN_REQUIRED GDK_VERSION_3_14
  #define  GDK_VERSION_MAX_ALLOWED GDK_VERSION_3_14

into glib-compat.h

For that matter we can update our min version to 3.18 I believe
since that looks like the oldest version any supported build
platform has.

Daniel
