Author: jng

New Revision: 7702

Modified:
   sandbox/jng/http304/Web/src/HttpHandler/HttpGetTileImage.cpp
Log:
Check in v2.6.0 GETTILEIMAGE support. This is currently blowing up (MgInvalidStreamHeaderException) due to some strange quirk in MgTile deserialization that is boggling my mind at the moment.
