	# Testing "Chainable Compositing Filters" from RFC113
	#
	# Test command: map2img -m layer_comp.map -o layer_comp.png
	# tested with: MapServer version 7.7-dev, but should work with 7.4 and 7.6
	#
	# documentation from mapservers-users list
#
#  COMPFILTER
# The currently available filters are:
# - "blur(integer)"
# - "translate(integer,integer)"
# - "grayscale()"
# - "blacken()"
# - "whiten()"
# 
# The COMPOP values that can be used should be explicit 
# and are listed here:
# clear
# color-burn
# color-dodge
# contrast*
# darken
# difference
# dst
# dst-atop
# dst-in
# dst-out
# dst-over
# exclusion
# hard-light
# invert*
# invert-rgb*
# lighten
# minus*
# multiply
# overlay
# plus
# screen
# soft-light
# src
# src-atop
# src-in
# src-out
# src-over
# xor

# Operators marked with a star (*) will only 
# be supported when using an AGG backends and 
# when pixman support is not enabled, 
# and will fall back to “src-over” when this is not the case.
