From Chris Denham, Implementation of write functions in CURL plugin
From Farshid Lashkari, "Attached is a simple fix to osg::Sequence that allows it to load properly with the serializer formats (osgt/osgb). The problem was that the internal _nrepsRemain member was not being initialized properly if the number of repeats was equal to the default value of -1. When the number of repeats is explicitly set using setNumRepeats(), _nrepsRemain is set to the same value. However, in the constructor of osg::Sequence, it was not being initialized to the same value as _nreps. This fix simply changes the initial value of _nrepsRemain to the same as _nreps."
Fixed the return value of SlideEventHandler::selectLayer() so that the 'n' now works correctly.
From Alberto Luacus, "The ffmpeg plugin fails to compile with the upcoming libav 0.8 because
the required header mathematics.h is not being included explicitly.

I have just included it, and verified that this also works with current
version 0.7, since the header is also available there."
Changed float QuicktimeImageStream::getCurrentTime() to double QuicktimeImageStream::getCurrentTime() to keep it consistent with
the type of the virtual function ImageStream::getCurrentTime(), and with this fixing a compile and runtime error.

Changed time variables all to use doubles rather than float to be consist with the change to getCurrentTime().
Refactored the click_to_run implementation to avoid bug associated with running the first click_to_run entry in a layer when
subsequent click to run's are called.
Added support for using GL_UNPACK_ROW_LENGTH in conjunction with texture's + osg::Image via new RowLength
parameter in osg::Image.  To support this Image::setData(..) now has a new optional rowLength parameter which
defaults to 0, which provides the original behaviour, Image::setRowLength(int) and int Image::getRowLength() are also provided.

With the introduction of RowLength support in osg::Image it is now possible to create a sub image where
the t size of the image are smaller than the row length, useful for when you have a large image on the CPU
and which to use a small portion of it on the GPU.  However, when these sub images are created the data
within the image is no longer contiguous so data access can no longer assume that all the data is in
one block.  The new method Image::isDataContiguous() enables the user to check whether the data is contiguous,
and if not one can either access the data row by row using Image::data(column,row,image) accessor, or use the
new Image::DataIterator for stepping through each block on memory assocatied with the image.

To support the possibility of non contiguous osg::Image usage of image objects has had to be updated to
check DataContiguous and handle the case or use access via the DataIerator or by row by row.  To achieve
this a relatively large number of files has had to be modified, in particular the texture classes and
image plugins that doing writing.
Fixed compile error
From Paul Martz, Added ViewerBase::s/getEndBarrierOperation(..) method to allow user control of how viewers are sync'd.
Moved setEndBarrierOperation(..) implementation into .cpp and added support for stoppig and starting threading if required.
Chris Denham, fixed type of parameters to ensure they are longs where appropriate.
From Paulk Martz, "Looks like the ClipNode::setReferenceFrame comment block came from LightSource. Fixing the comment block to refer to ClipNode instead of light source."
Fixed indentation and spaces at ends of lines.
From Tobias Ottenweller, "this is a fix for the problem where all input freezes for a quarter second when calling requestWarpPointer under Mac OS X (described here: http://forum.openscenegraph.org/viewtopic.php?t=3933 ).

I used the latest version available via subversion.

My fix is using some API only available on 10.4 and later. I used some preprocessor statements to gain compatibility with 10.3 and earlier using (now) deprecated API.

Only tested on OS X Lion (10.7). Please do some testing as well since I'm fairly new to OpenSceneGraph. Someone should also test the code for 10.3 and earlier."
Made the cursor state protected.
Changed the KeyEventToggleTexturing to 'e' to avoid conflict with 't' used for transparency.
From Luc Frauciel, "Ati FirePro is as much crippled as other Ati drivers.
This patch add "FirePro" to the black list of renderers in State.cpp / initializeExtensionProcs

It allows to avoid an OpenGL error on Viewer initialization.
Tested on FirePro  M7740 / Windows7 x64  Driver 8.85.7.2"
From J.P. Delport, "GraphicsWindowX11 typo, I believe X/Y's should match."
From J.P. Delport, "this fall-through had me scratching my head for a while...

It made InteractiveImageHandler eat keypresses outside its image."
From J.P. Delport, "when switching from windowed mode to fullscreen (with the 'f' key) in X11, no RESIZE event is generated. This confuses handlers that perform some processing on the RESIZE event, e.g. the InteractiveImageHandler.

To reproduce the problem I attach a minimally modified osgviewer that just prints resize events. You can check what's printed in the console when you go fullscreen and windowed a few times.

The attached version of GraphicsWindowX11 fixes the problem for me, but I'm not sure this is the right approach. Maybe you can see a fix for the problem clearer.

The only place where the RESIZE event is generated in GraphicsWindowX11 is in CheckEvents and it then depends on the ConfigureNotify message. For some reason, either ConfigureNotify is not sent when going fullscreen or the traits already reflect the latest window size."
