# NAME: etr_slipUValert.py
# VERS: 1.0
# DATE: May 27, 2014
#
# MADE: Cristobal Vila, etereaestudios.com
#
# USES: This is a dirty hack to help with Slip UVs detection.
#		What this script does is to toggle Slips UVs and, at the same time, toggle a yellow border
#		(using 'anim.setup on / off') to indicate when that option is enabled or not.
#		It works even when Transform tools are not enabled.
#		IMPORTANT NOTE: change Slip UV Startup State Pref to "Last Selected" in MODO 801.
#
# TODO: Change automatically to 3D viewport (if any is available) if a non-3DVP is selected.
#		Change automatically to a comp sel mode if a non-comp mode is in use. Return to original at end.
