#
# 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.
