     <function>swfbitmap</function> creates a new SWFBitmap object from 
     the Jpeg or DBL file named <parameter>filename</parameter>. 
     <parameter>alphafilename</parameter> indicates a MSK file to
     be used as an alpha mask for a Jpeg image.

      We can only deal with baseline (frame 0) jpegs, no baseline optimized or 
      progressive scan jpegs!

     SWFBitmap has the following methods : <function>swfbitmap->getwidth</function>
     and <function>swfbitmap->getheight</function>.

     You can't import png images directly, though- have to use the png2dbl 
     utility to make a dbl ("define bits lossless") file from the png. 
     The reason for this is that I don't want a dependency on the png library 
     in ming- autoconf should solve this, but that's not set up yet. 
     <example>

<?php
  $s = new SWFShape();
  $f = $s->addFill(new SWFBitmap("png.dbl"));

  $s->drawLine(32, 0);
  $s->drawLine(0, 32);
  $s->drawLine(-32, 0);
  $s->drawLine(0, -32);

  $m = new SWFMovie();
  $m->setDimension(32, 32);

     And you can put an alpha mask on a jpeg fill.
