   SWFDisplayItem->rotateTo -- Rotates the object in global coordinates.

Description

   void swfdisplayitem->rotateto ( float degrees)

   Warning

   This function is EXPERIMENTAL. The behaviour of this function, the
   name of this function, and anything else documented about this
   function may change without notice in a future release of PHP. Use
   this function at your own risk.

   swfdisplayitem->rotateto() set the current object rotation to degrees
   degrees in global coordinates.

   The object may be a swfshape(), a swfbutton(), a swftext() or a
   swfsprite() object. It must have been added using the swfmovie->add().

   This example bring three rotating string from the background to the
   foreground. Pretty nice.

   Example 1. swfdisplayitem->rotateto() example
   <?php
     $thetext =  "ming!";
     $f = new SWFFont("Bauhaus 93.fdb");
     $m = new SWFMovie();
     $m->setRate(24.0);
     $m->setDimension(2400, 1600);
     $m->setBackground(0xff, 0xff, 0xff);
     // functions with huge numbers of arbitrary
     // arguments are always a good idea!  Really!
     function text($r, $g, $b, $a, $rot, $x, $y, $scale, $string) {
       global $f, $m;
       $t = new SWFText();
       $t->setFont($f);
       $t->setColor($r, $g, $b, $a);
       $t->setHeight(960);
       $t->moveTo(-($f->getWidth($string))/2, $f->getAscent()/2);
       $t->addString($string);
       // we can add properties just like a normal PHP var,
       // as long as the names aren't already used.
       // e.g., we can't set $i->scale, because that's a function
       $i = $m->add($t);
       $i->x = $x;
       $i->y = $y;
       $i->rot = $rot;
       $i->s = $scale;
       $i->rotateTo($rot);
       $i->scale($scale, $scale);
       // but the changes are local to the function, so we have to
       // return the changed object.  kinda weird..
       return $i;
   }
     function step($i) {
       $oldrot = $i->rot;
       $i->rot = 19*$i->rot/20;
       $i->x = (19*$i->x + 1200)/20;
       $i->y = (19*$i->y + 800)/20;

       $i->moveTo($i->x, $i->y);
       return $i;
     }
     // see?  it sure paid off in legibility:
