implementations being registered at the same time.
One usage case for this functionality to support usage of Wayland and X11 in the same version of the osgViewer.
As part of the new functionality there is now a osg::GraphicsContext::Traits::windowingSystemPreferrence string
that default to empty, but if defined will ensure that a specific WindowingSystemInterface is utilized when
you do a generic call like osg::createGraphicsContext().
Also implemented is standard proxy object for registering the new contexts and removing them automatically, and
declaration of standard graphicswindow_name() C entry point to help with static build linking.
If OSG_OPENGL_PROFILE="GLES3" =>
GraphicsWindowIOS will create gles3 context.
If failed, GraphicsWindowIOS will create gles2 context.
Multisampling also working.

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.
"
* force _OPENTHREADS_ATOMIC_USE_BSD_ATOMIC for IOS device + simulator as the test does not pick the right implementation
* fixed a small compile-bug for iphone-example
* added a check to prevent multiple realization of a GraphicsWindowIOS-object
"
* fixed a bug with multi-touch and touch-id-generation on iOS and OS X. (will fix a bug reported by Colin Cochran, without ditching the existing logic)
* removed unnecessary warning-flagss when generating xcode-projects via cmake, will enable the usage of OSG_AGGRESSIVE_WARNING_FLAGS
* added support for 10.9 (OS X)
* new cmake-variable: IPHONE_VERSION_MIN, this will set the deployment-target (previously hard-coded) If you set the IPHONE_VERSION_MIN to something like 7.0 osg gets compiled also for 64bit (amd64)
* cmake defaults now to the clang compiler if IPHONE_VERSION_MIN > 4.2
* cmake now sets some xcode-settings so the compiler uses the c++98-standard (clang defaults to c++11, w/o this I got a lot of linking errors)
* removed include-dir for avfoundation-plugin as not needed on OSX/IOS.
* enhanced the ios-example, will now show multitouch-information on a hud (similar to the osgmultitouch-example), and more importantly, will compile + link out of the box
* small enhancements for the osc-device-plugin (send only one msg for MOVE/DRAG, even if multiple msgs/event is enabled)
* better memory-handling for the zeroconf-plugin
* fixed a possible bug in the rest-http-plugin when receiving mouse-events.
* incorporated a fix from Colin Cochran "forwarded touch events are not transformed into the GL UIView“
"
The solution for to refactor the way that events are checked so I add a bool return type to checkEvents() method across osgViewer::GraphcisWindow, osgGA::Devive and osgViewer::Viewer/CompositeViewer classes
* 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.

The impact of the bug was a memory leak that would affect multi-sampling iOS apps that allow for device rotation or window resizing in general. For our app, the leak ranged from ca. 10 MB to 40 MB per device rotation, depending on device, for the MSAA buffers. I have not been able to confirm impact for the stencil buffer. "
Attached are changes to GraphicsWindowIOS.mm to support setting up the new buffer type when compiling for iOS5,
also attached is a small change to FrameBufferObject.cpp to report support for packed depth stencil via the
GL_OES_packed_depth_stencil extension.
For anyone reading this you can attach a packed depth stencil to your FBO like so
_rttCamera->attach( osg::Camera::PACKED_DEPTH_STENCIL_BUFFER, GL_DEPTH24_STENCIL8_EXT );
Luckily GL_DEPTH24_STENCIL8_EXT happens to have the same value as iOSs GL_DEPTH24_STENCIL8_OES"
Here's another small submission for IOS, which adds unique ids to the
touchpoints, so the ids stay the same during a touch-sequence.
(and some minor code enhancements)"

for GraphicWindowsIOS.mm broke the compilation for OpenGL ES 1.x as
GL_DEPTH_COMPONENT32_OES is not defined for 1.x. I added a #define-guard."
UIView, respecting the sizes via GraphicsContext::Traits.
This helps users, who want to integrate osg into an existing ios-app
with multiple UIViews. Additinally a view-controller gets only created
if needed, set IGNORE_ORIENTATION via the WindowData-struct.
"
enum DeviceOrientation{
PORTRAIT_ORIENTATION = 1<<0,
PORTRAIT_UPSIDEDOWN_ORIENTATION = 1<<1,
LANDSCAPE_LEFT_ORIENTATION = 1<<2,
LANDSCAPE_RIGHT_ORIENTATION = 1<<3,
ALL_ORIENTATIONS = PORTRAIT_ORIENTATION | PORTRAIT_UPSIDEDOWN_ORIENTATION | LANDSCAPE_LEFT_ORIENTATION | LANDSCAPE_RIGHT_ORIENTATION
};
typedef unsigned int DeviceOrientationFlags;
The main motivation for this is to easily allow the user to specifiy that the device is in a horizontal orientation rather then having to rotate the view matrix. All flags have been tested individually as well as in combinations. The default is ALL_ORIENTATIONS to keep the exiting functionality for anyone who hasn't specified WindowData for their context traits.
"
attached you'll find the second part of the IOS-submission. It contains
* GraphicsWindowIOS, which supports external and "retina" displays,
multisample-buffers (for IOS > 4.0) and multi-touch-events
* an ios-specific implementation of the imageio-plugin
* an iphone-viewer example
* cMake support for creating a xcode-project
* an updated ReadMe-file describing the necessary steps to get a
working xcode-project-file from CMake
Please credit Thomas Hogarth and Stephan Huber for these changes.
This brings the ios-support in line with the git-fork on github. It
needs some more testing and some more love, the cmake-process is still a
little complicated.
You'll need a special version of the freetype lib compiled for IOS,
there's one bundled in the OpenFrameworks-distribution, which can be used."
Notes, from Robert Osfield, modified CMakeLists.txt files so that the IOS specific paths are within IF(APPLE) blocks.
