-- Concept : translate SVG file in GEO .obj file and try to load it. 
-- 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

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 followed by a lone data 
                (h,v) or uncommun number (a) 
      0.2.5 : - correction for gimp import 
      0.2.6 : - correction for illustrator 10 SVG
      0.2.7 : - correction for inskape 0.40 cvs  SVG
      0.2.8 : - correction for inskape plain SVG
      0.3   : - reading of the transform properties added : 
                    translate
      0.3.1 : - compatibility restored with gimp 
      0.3.2 : - transform properties added (june, 15-16): 
                    scale, 
                    rotate, 
                    matrix, 
                    skew               
              - added a test on __name__ to load the script
                outside from the blender menu  
      0.3.3 : - controle du contenu des transformation de type matrix 
      0.3.4 : - restructuration de la lecture des donnes paths (19/06/05)
