blender/release/scripts/mod_svg2obj.py
Willian Padovani Germano 452c8cf838 Done. 
Scripts:
- Jean-Michel Soler probably lost some hours of sleep since Sunday,
  but he managed to send me the updated path import scripts a few
  hours ago.  My tests with Inkscape .svg and .ps and Gimp worked fine.
  He also tested a lot and sent me info about what is already
  supported.  I'll send Ton a doc about bundled scripts including this
  info.  Importers: .ai, .svg, .eps/.ps, Gimp 1-1.2.5 / 2.0.

- Jean-Michel also contributed his Texture Baker script.

- Campbell Barton contributed two new scripts: a mesh cleaner and a
  vloop skinning / lofting script.  He also sent updates to his obj
  import / export ones.

- A Vanpoucke (xand) contributed his Axis Orientation Copy script.

And that makes 8 last minute additions.  Thanks a lot to the authors
and special thanks to JMS and Campbell for their hard work : ).

BPython:

- tiny addition (I'm forced to call it a showstopper bug ;) so JMS's
path import scripts (that actually convert to obj and make Blender
load the .obj curves) can use Blender.Load() and not rename G.sce,
the default filename.  Blender.Load(filename, 1) doesn't update G.sce.
Nothing should break because of this, Load(filename) still works fine.

- Made Blender complain again if script is for a newer Blender version than the one running it.

-- Concept : translate SVG file in GEO .obj file and try to load it.
-- Real problem : the name of the blender file is changed ...
-- Curiousity : the original matrix must be :
0.0 0.0 1.0 0.0
0.0 1.0 0.0 0.0
0.0 0.0 1.0 0.0
0.0 0.0 0.0 1.0
and not:
1.0 0.0 0.0 0.0
0.0 1.0 0.0 0.0
0.0 0.0 1.0 0.0
0.0 0.0 0.0 1.0
-- Options :
SHARP_IMPORT = 0
choise between "As is", "Devide by height" and "Devide by width"
SHARP_IMPORT = 1
no choise
-- Possible bug : sometime, the new curves object's RotY value
jumps to -90.0 degrees without any reason.
Yet done:
M : absolute move to
Z : close path
L : absolute line to
C : absolute curve to
S : absolute curve to with only one handle
l : relative line to 2004/08/03
c : relative curve to 2004/08/03
s : relative curve to with only one handle
To do: A,S,V,H,Q,T,
a,s, m, v, h, q,t
Changelog:
0.1.1 : - control file without extension
0.2.0 : - improved reading of several data of the same type
following the same command (for gimp import)
0.2.1 : - better choice for viewboxing ( takes the viewbox if found,
instead of x,y,width and height
0.2.2 : - read compact path data from Illustrator 10
0.2.3 : - read a few new relative displacements
0.2.4 : - better hash for command with followed by a lone data
(h,v) or uncommun number (a)
