# Select all objects in the current layer with the same line color as
# the currently selected object. This is implemented as an advanced
# script. It doesn't have to deal with undo because it only changes the
# set of currently selected objects and not the objects themselves.
#
# Conceps and Methods:
#
# CurrentProperties():
#
# This document method returns the properties of the currently
# selected object. If more than one objects are selected or no
# object is selected or the selected object doesn't have
# properties, a special property object EmptyProperties is
# returned.
#
# Now, what does this mean? Objects like rectangles, text and
# curves have graphics properties like fill or line patters, line
# width or font whatever is applicable for that particular type.
# Some obejcts have no graphics properties at all, e.g. groups,
# while others can only have some properties, e.g. text objects
# currently can't have a line color (this is really a limitation
# in X11, PostScript wouldn't have problems with that).
#
# All of the properties are stored in a properties object, and
# that is what the CurrentProperties() method returns. Such a
# properties object has three methods that indicate whether the
# fill-, line- or text properties are valid: HasFill(), HasLine()
# and HasFont(). Only if one of those methods returns true, can
# you safely access the respective properties. The properties are
# publicly readable attributes of the properties object. For the
# EmptyProperties object that may be returned by
# CurrentProperties(), all of these methods return false.
