* sea/src/sxlib2LEF.c, 

sea/src/LEF_drive_sxlib.h,
   sea/src/LEF_drive_sxlib.c,
   sea/src/a2lef.sh :
   - Nouvelle option : il devient possible de ne pas decomposer les
       segments connecteurs en rectangles poses sur la grille de
       routage, les segments ne sont pas gardes tel quels. Ils sont
       mis a la largeur minimale et leurs extremites ramenees a la
       largeur minimale.
         ATTENTION : il n'y pas de verification que des segments se
       chevauchent. Dans ce cas il y generation de segments superposes.
         Option de a2lef     : "-T".
         Option de sxlib2lef : "-t".
