Int_t WriteGIF(char* name)
 Writes the current active window into pixmap file.
 The format is defined by the file name extension
 like "png","jpg","bmp"  . . .
 If no extension is provided the "png" format is used by default

 Returns 1 in case of success,
         0 otherwise
 Note: this method may not produce the expected result been called
 ----  from the ROOT prompt by simple reason:
       The active window will be console window
