# performs a [subst] on the class declaration before evaluating
# it. This gives us a chance to specify platform-specific widget
# default without using a lot of ugly double quotes.
#
# The use of subst'able entries in the class declaration should
# be restrained to widget default values only to avoid producing
# unreadable code.
#
# Arguments:
# name - The name of the class to declare.
# classDecl - Various declarations about the class. See documentation
# of tixWidgetClass for details.
