Description

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.
