Updated ChangeLog
From Ulrich Hertlein, "Attached is a patch that introduces 'static_cast<unsigned int>' on some instances where
the code returns '.size()' of a std::vector.  This caused some warnings when using clang++
on OS X."
From Farshid Lashkari, "The tga image loader was not properly reading in 16-bit images. Fix is attached."
From Michael Kapelko, "The provided patch (against SVN revision 13380) adds missing constness to returning calls (without it the user code does not compile)."
From Lionel Lagarde, "When a function do:

OSG_DEBUG << "Hello world!\n";

the underlying stream is not automatically flushed. It is flushed
if endl is queued instead of \n:

OSG_DEBUG << "Hello world!" << std::endl;


The notify macros do:
stream->setCurrentSeverity(severity);
return *stream;

So, if a function do:

OSG_DEBUG << "This is a debug message\n";
OSG_NOTICE << "This is a notice message" << std::endl;

the debug message will be classified as a notice message.

It is a problem when the application uses a NotifyHandler. The notify
method of the handler is called with:

severity = NOTICE
message = "This is a debug message\nThis is a notice message"

The attached Notify.cpp contains an automatic flush of the stream when
the current severity changes.
