This feature makes it easier to editor an presentation that is already running in Present3D, once the edits are done
pressing 'u' in Present3D then loads the file again.
forcing users to use osgDB::readRef*File() methods. The later is preferable as it closes a potential threading bug when using paging databases in conjunction
with the osgDB::Registry Object Cache. This threading bug occurs when one thread gets an object from the Cache via an osgDB::read*File() call where only
a pointer to the object is passed back, so taking a reference to the object is delayed till it gets reassigned to a ref_ptr<>, but at the same time another
thread calls a flush of the Object Cache deleting this object as it's referenceCount is now zero. Using osgDB::readREf*File() makes sure the a ref_ptr<> is
passed back and the referenceCount never goes to zero.
To ensure the OSG builds when OSG_PROVIDE_READFILE is to OFF the many cases of osgDB::read*File() usage had to be replaced with a ref_ptr<> osgDB::readRef*File()
usage. The avoid this change causing lots of other client code to be rewritten to handle the use of ref_ptr<> in place of C pointer I introduced a serious of
templte methods in various class to adapt ref_ptr<> to the underly C pointer to be passed to old OSG API's, example of this is found in include/osg/Group:
bool addChild(Node* child); // old method which can only be used with a Node*
tempalte<class T> bool addChild(const osg::ref_ptr<T>& child) { return addChild(child.get()); } // adapter template method
These changes together cover 149 modified files, so it's a large submission. This extent of changes are warrent to make use of the Object Cache
and multi-threaded loaded more robust.

I added a new tag to p3d called forward_touch_event_to_device and renamed the existing forward_event_to_device to forward_mouse_event_to_device. This new tag will transmit touches to the virtual trackpad as touch events. I added the MultitouchTrackball to the p3d-app so zooming and moving a model remotely should now work, if you use forward_touch_event_to_device. I kept (and fixed) forward_mouse_event_to_device for background compatibility, so old presentations works as in previous versions, without the ability to zoom + scale. of course.
forward_touch_event_to_device needs some more testing, (e.g. with image-streams and keystone, afaik there’s no support for touch-events...) but for a first version it works nice.

Examples of supported matches are:
<Slide> and <slide> will be treated the same
<bgcolor>WHITE</bgcolor> and <bgcolor>White</bgcolor> will be treated the same
<text alignment="TOP_LEFT"</text> and <text alignment="top left"</text>, <text alignment="TopLeft"</text> will all be treated the same
* a new command-line-option to present3d and a new option to the p3d-plugin to suppress any found <env> tags
* a new command-line-option to present3d to forward mouse-events via osgGA::Device (defaults to off) so we can test the interface-files with present3d better
* I added a new attribute forward_to_devices for click_to_event to forward the event to all attached devices instead of handling the event locally. This will fix the annoyance with the new interface-files when toggling polygon-mode or switching light on/off.
Here’s an example:
<click_to_event forward_to_devices="true">0x72</click_to_event>

* resthttp/osc: encapsulate RequestHandler-classes in their own namespaces to prevent class-name-lookup-errors in the debugger/code (had some weird crashes)
* QTKit: fixed a compile-bug for gcc and blocks
* osgPresentation: click_to_* will fire on RELEASE, only if the drawable received a PUSH beforehand
* p3d/osgPresentation: implemented "forward_mouse_event_to_device"-tag, which will forward mouse-events to all registered devices of a viewer, if an intersection occurs. The mouse-coordinates get reprojected
* present3d: all devices get registered with the viewer
* osgViewer: only devices which are capable of receiving events are queried for new events.
* GraphicWindowIOS: added a flag to GraphicWindowIOS::WindowData to set up a retained backing buffer (defaults to false) This will enable read-back of the render-buffer with glReadPixels even after the renderbuffer got presented
* curl: added an optimized check for file-existance, now only the headers are requested and checked, instead of reading the whole file and handle it with a ReaderWriter
* p3d: fixed a bug, where the existence of a local file may prevent the remote loading of a file with the same name.

* ZeroConfDevice does now return FILE_NOT_HANDLED instead of FILE_NOT_FOUND
* present3D supports multiple devices per env-var P3D_DEVICE, separate multiple device with a space
I refactored parts the p3d-plugin, the curl-plugin and parts of Registry and ReaderWriter. Currently the p3d-plugin tries to open all remote files with the help of the curl-plugin.
I added a new method to Registry called getReaderWriterForProtocolAndExtension. which will return a ReaderWriter which is capable in handling the remote file for the given protocol and extension. If no readerwriter is found for the given extension, a list is built of all readerwriters supporting the given protocol and this list is checked for support of wildcards (extension = "*"). If anything matches it get returned.
I added this principle also to the Registry, so now it's possible to register a generic ReaderWriter which can handle all filetypes for a given protocol, similar what curl is doing. All you have to do is to load the plugin at startup. The curl-fallback is still in place.
With these changes it is now possible to reference a movie inside a presentation without a server-address, read the presentation (with curl) and stream the movie with the correct plugin (e.g. QTKit)
