           Summary: XMLGraphics does not accept SAXSource'd images anymore
                    after the latest image loaders changes [w-patch]
           Product: XMLGraphicsCommons
           Version: Trunk
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: Utilities
        AssignedTo: general@xmlgraphics.apache.org
        ReportedBy: ono@java.pl

XMLmind XMLEditor is using custom URI resolver for FOPFactory, for all resolved URIs it is
returning 
SAXSource rather than StreamSource.
Before 1.3 and latest FOP changes, images were loaded properly, but with latest trunk of FOP
I started 
getting: [FOP Error] No ImagePreloader for ... and then Cannot open image (because URI was
cached as 
wrong).

After hours of digging I found out that URI resolver of XMLmind is returning always SAXSource,
while src/java/org/apache/xmlgraphics/image/loader/impl/AbstractImageSessionContext.java @
newSource 
expects StreamSource. Also image loaders work only with ImageSource, that was created only
from 
StreamSource, with generic Source they fail.

I'm attaching patch for AbstractImageSessionContext.java that checks also for SAXSource and
allows 
using its inputSource's byte stream.

This makes XMLmind FOP addon again usable with latest FOP trunk.
