    reftests: Add a shell script to create tests
    
    See the documentation in the script.
    Tests are not yet added as the output from the 2 included scripts
    doesn't match and the intended reference output first needs to be agreed
    on.

+# align-expand.sh [METHOD]
+#
+# This is the script used to create the align-expand tests. These tests
+# put a 20x20 size-requested GtkTreeView into a 40x40 size-requested
+# container and try to achieve multiple combinations of expand and align
+# flags. The resulting GtkBuilder file is written to stdout. All of the
+# resulting files should render identical.
+#
+# METHOD is one of:
+# * flags (default)
+#   Uses expand flags to align and expand the treeview inside a GtkGrid.
+#   You should use this as the reference when adding tests for other
+#   methods
+# * alignment
+#   Aligns and expands the treeview in a GtkAlignment using its scale
+#   and align properties.
