Bugzilla #37330:

1) The jpeg registration now includes the hashCode in addition
   to the jpegCount as this prevents images being rused when
   multiple SVG fragments are included in a single FO.
2) Added a createBridgeContext to PDFBridgeContext so that 'sub contexts'
   (image element) inherit the new bridges.
