Willian Padovani Germano e5b527c629 Scripts: 
- Jean-Michel Soler updated his paths importer (svg part) -- ongoing work related to this bug report by intrr:
http://projects.blender.org/tracker/?func=detail&atid=125&aid=2674&group_id=9

- small doc update in paths import about some imported curves needing "enter edit mode, select all points, toggle cyclic (press 'c')" to show up correctly;

- old vrml 2 exporter's menu name and tooltip updated to clarify that it is the old version, soon to be removed (in favor of the already included vrml 97 update by Bart).  Also prints a msg about it to the console when used.

Thanks all.

# To use script:
# 1.) load this file in the text window.
# (press SHIFT+F11, Open New via Datablock button)
# 2.) make sure your mouse is over the text edit window and
# run this script. (press ALT+P)
# Or:
# copy to the scripts directory and it will appear in the
# export list. (Needs 2.32 or higher)
#
# Notes:
# a.) output filename is same as current blender file with .wrl extension
# b.) error messages go to the Blender DOS console window
#
# The latest version of this python export script:

# If you like this script, try using http://vrmlworld.net/
# to show off your VRML world.
#
# 2004-01-19 by Rick Kimball <rick@vrmlworld.net>
# o added sub menus and file selector dialog
#
# 2004-01-17 by Rick Kimball <rick@vrmlworld.net>
# o add meta comments so script will appear in export menu list
#
# 2003-11-01 by Rick Kimball <rick@vrmlworld.net>
# o fixed issues related to Lamp object and 2.28a API.
#
# 2003-07-19 by Rick Kimball <rick@vrmlworld.net>
# o made compatible with new Python API in 2.28
#
# 2003-01-16 by Ken Miller - with math help from Steve Matthews :)
# o Added support for exporting cameras out of Blender
# o Sets the name of the camera as the object name
# o sets the description of the camera as the object name,
# which should be modified to something meaningful
# o sets the position and orientation
#
# 2003-01-19 Rick Kimball <rick@vrmlworld.net>
# o Added Support For PointLight, SpotLight and DirectionalLight using Lamps
# o Creates multi singlesided or doublesided IFS
# o Creates IndexedLineSets if DrawTypes is WIRE instead of Shaded
#
# 2003-02-03 Rick Kimball <rick@vrmlworld.net>
# o attempts to catch exceptions for empty objects
#
# 2003-02-04 Rick Kimball <rick@vrmlworld.net>
# o fixed file overwrite problem when blender filename is all uppercase
#
# 2003-02-08 Rick Kimball <rick@vrmlworld.net>
# o cleanStr() creates valid VRML DEF names even if object.name
# is zero length or uses VRML reserved names or characters
#
#------------------------------------------------------------------------
# Known Issue:
# o doesn't handle multiple materials (don't use material indices)
# o doesn't handle multiple UV textures on a single mesh. (create a mesh for each texture)
# o material colors need work
# o spotlight softness needs work
# o can't get the texture array associated with material * not the UV ones
# o can't set smoothing, crease angle and mesh smoothing * setting not accesible
#
# Still Todo:
#
# - Support for material indexes
# - Automatically Split IFS when multiple UV textures found * warning only now
# - Automatically Split IFS when combination of single vs double sided
# - Automatically Split IFS when face with only 2 vertices is found should be an ILS
# - Export common coordinate map for split IFS
# - Intelligent color array vs color index
# - Support more blender objects: World
# - Figure out how to output Animation
# - Add GUI to control the following:
# o All/Layer/Object output radio button
# o Color per vertex toggle yes/no
# o Complex/Simple VRML output radio button
# o Compressed/Uncompressed output radio button
# o Decimal precision dropdown 1,2,3,4,5,6
# o IFS/Elevation Grid output radio button
# o Normals output toggle yes/no
# o Proto output toggle yes/no
# o Verbose console progress
