Image cache reused after being cleared.

[GoogleCodeExporter]

What steps will reproduce the problem?

Create a PDF with images, destroy the dompdf object then create another PDF 
using the same images from within the same working script.  The cached images 
are removed but the cache array is not resulting in the 2nd creating failing to 
read the images.

What version of dompdf are you using? 

This affects the current trunk as well as an old copy I had back from early 
last year.  

Fix is to reset the array in the Image_Cache::clear()

static function clear() {    
    if ( empty(self::$_cache) || DEBUGKEEPTEMP ) return;

    foreach ( self::$_cache as $file ) {
      if (DEBUGPNG) print "[clear unlink $file]";
      unlink($file);      
    }

    @@ self::$_cache = array();
  }

You are right, my mistake! I didn't notice that the array was emptied, when I 
did a refactoring of this class.
