 Attempting to serialize a MgRaster with palette information will crash the
 MapGuide Server.

 The problem is that the m_palette member is a MgByte, which does not
 inherit from MgSerializable, thus the resulting call to
 MgStreamWriter::WriteObject() performs an invalid cast on the MgByte to
 MgSerializable

 The solution is to either:

  * Implement a MgSerializable wrapper for MgByte objects
  * Use a non-WriteObject method for serializing the MgByte object (not
 sure if this can be done)
