One solution is naturally to create a new class that would inherit the osg::ComputeBoundVisitor, and use that. I don't like that idea as the ComputeBoundVisitor does actually have what I need - it is only hidden in a protected function.
I am therefor suggesting a slight generalization of the ComputeBoundVisitor with the attached patch, which is tested.
The patch has two parts:
we add applyBBox() so that one can use that in a customized traverse-function and add a bbox to the visitor. I considered calling this function expandByBBox(), but I though applyBBox was better.
The MatrixStack is made available to the outside world. That enables a traverse-function to do whatever it wishes.
I do actually only need one of the two, as I can implement what I wish either way, but adding getMatrixStack() will make more generic expansions possible.

From Robert Osfield, changed the name of the new applyBBox(..) method to applyBoundingBox(..) to keep it's naming more consistent with the rest of the OSG.
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
From Robert Osfield, changed Roni's code to use a #define GETDEVICEPIXELRATIO to access the versioned Qt devicePixelRatio() method to avoid duplication of the Qt version checking.
I have tested this on:
mac/qt5.2
linux/qt5.2
windows/qt5.2, and
mac/qt5.1
All platforms perform as expected.
The previous fix removed the -f flag to the moc-pre-processor, but on windows, it turned out that -f "osgQt/QGraphicsViewer" was needed.
This becomes an include-statement in the file generated by moc which is needed for compiling it. I ask you consider this patch for the trunk and the 3.2 branch.
Secondly, I wonder if it would be possible to apply my patch for FindRSVG.cmake from 22nd November in the 3.2 branch.
In short, the version of librsvg must be equal or higher to 2.35:
PKG_CHECK_MODULES(RSVG librsvg-2.0>=2.35)

Updated lua plugin to use new osgDB::PropertyInterface to run methods.
Added addChild/removeChild() etc to Group.cpp, and addDrawable/removeDrawable() etc. to Geode.cpp serializers.
Hence, moc will complain when osg throws in a -f without anything after it. Hence I propose removing the -f on Qt5 builds. I have tested building without -f on both qt520 and qt511, and that works well.
The attached src/osgQt/CMakeLists.txt that can be patched into 3.2 safely. For the trunk, I would consider dropping the check on the version, and simply remove the option on qt5. I have tested that on qt5.1.1, and that worked fine. Question is however if it works on qt5.0. Probably it does, so the question is simplicity of CMakeList.txt vs safety."

* 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>
"
* osgDB::FileUtils uses now the Cocoa-API to determine the paths of the application-support-folder
* DarwinUtils uses now modern functions of the quartz-api to get and set screen-resolutions. Removed some of the osg-deprecated stuff.
