The calibrator gets a GdkDevice from the GtkGesture but that device is
the "Logical device for $TABLET", not the actual device. So all our
clicks are discarded as coming from the wrong device.
Fix this by passing the GsdDevice through and comparing against that.
Closes#1871
Same dog, different collar. The UI has been ported 1:1 to GTK+, using
GtkBuilder, CSS and event controllers fairly reduced the amount of code
needed for this.
It also allows us to stop initializing clutter-gtk across the several
executables.
Meson is a build system focused on speed an ease of use, which
helps speeding up the software development. This patch adds meson
support along autotools.
