HOW TO USE:
 *Select pathes and drag.
 *Release mouse button to fix the result.
OPTIONS:
  focal length:  distance to focal point
  global depth: default depth (negative value for z-axis)
  fix z-order: (see OTHER NOTE below)
BE CAREFULL NOT TO DO SUBSEQUENT DRAGS:
 *Once mouse button was released, the targets' z-axis values are
  set to zero, and they return to 2D plane, as distorted shapes.
  So, if you select these transformed targets and drag again,
  the result must be a quite unexpected one.
  If you don't prefer the result, make undo first.
OPTIONS BY THE NAME OF THE TARGETS:
 *This script gets optional values from the name of the object
  as follows. (N means a number)
    N:   height ( - global depth) (must be at the beginning of its name)
    xN:  x-axis rotation. uses center of the object itself as origin
    xoN: x-axis rotation. uses global origin (default: center of the selection)
    yN, zN: same as "xN" but for y-axis and z-axis
    yoN, zoN: same as "xoN" but for y-axis and z-axis
    LN:  sets left side of the object as the self-rotation center
       if N specified, offsets the center by N toward center of the object.
    RN, TN, BN:  same for right, top, bottom
    ZN:  offsets the center of the self-rotation by N toward z-axis (front/rear)
ex. name="10 x20" -> rotates 20 degree around x-axis, rotation origin is the center of the object itself. then offsets the center of this object's z-axis value by 10.
*If there's a path named "origin" in the selection, this script set its center as the rotation center.
 *Here is an example Ai file.

OTHER NOTE:
 *If "fix z-order" option is checked, this script changes the z-order of the objects according to the z-axis value of the center of the each object. It doesn't always work properly, and this process may destruct the groups.
 *This script removes the transformed objects that had exceeded
  the value which multiplied the virtual sphere radius by predefined value with a message dialog. The default predefined value is 2.0.
  Edit "excessive_transform_threshold" value below to change it.

__*modified applying order:
__  self-rotation > height > global-rotation > global-height
__*If the parent of the target is an instance of Art ( unless it is not a Layer), gets options and applys recursively
2009-05-27a
__*added L,R,T,B,Z option.
__  see "OPTIONS BY THE NAME OF THE TARGETS" section for detail.
__*fixed a bug in "getArtSetRect" function
2009-06-30: *removed "min_radius" option
__*added "fix_z_order" option
