# BaseWBCanvas.itcl
#
# Interface between application code and the itcl runtime environment for
# tcl applets.
#
# An itcl applet inherits this class which makes a number of methods
# available from the actual application code.
#
# To be safe the code should run in a safe interpreter with all
# methods and variables in this base class aliased.
