# Test Arguments:
# name -                Name of test, in the form foo-1.2.
# description -         Short textual description of the test, to
#                       help humans understand what it does.
# constraints -         A list of one or more keywords, each of
#                       which must be the name of an element in
#                       the array "testConfig".  If any of these
#                       elements is zero, the test is skipped.
#                       This argument may be omitted.
# script -              Script to run to carry out the test.  It must
#                       return a result that can be checked for
#                       correctness.
# answer -              Expected result from script.

# One time setup.  Create a font to insure the tests are font metric invariant.
