methods
getProjectionMatrixAsOrtho()
getProjectionMatrixAsFrustum()
getProjectionMatrixAsPerspective()
getViewMatrixAsLookAt() (2x)
are now const, as they only call const methods of osg::Matrixf/d.

1. In WindowManager.cpp childRemoved method the second parameter "end" is misleading and
should be named "numChildren" instead. It represents how many children to remove. As a result, the method was implemented incorrectly and failed to remove UI objects. So I fixed it.
replaced this:
void WindowManager::childRemoved(unsigned int start, unsigned int end) {
while(start < end) {
Window* window = getByIndex(start);
if(!window) continue;
if(_remove(window)) {
window->_index = -1;
window->unmanaged(this);
}
start++;
}
}
with this:
void WindowManager::childRemoved(unsigned int start, unsigned int numChildren) {
for (unsigned int i = start; i < start+numChildren; i++)
{
Window* window = getByIndex(i);
if(!window) continue;
if(_remove(window)) {
window->_index = -1;
window->unmanaged(this);
}
}
}
2. in Input.cpp
The cursor in Input did not get positioned correctly, probably as a left over from the TOP LEFT origin system which is now BOTTOM LEFT.
in method positioned()
replaced this:
_cursor->setOrigin(x + xoffset + 1.0f, y - _cursor->getHeight() + 1.0f);
with this:
_cursor->setOrigin(x + xoffset + 1.0f, y + 1.0f);
Now it is placed correctly.

I've made a small change to Registry.cpp that puts the CURL logic AFTER the URL has been passed to the plugin rather than assuming all URL's need to be downloaded by the CURL plugin. This way, plugins can have first crack at the URL's, and if they don't handle it the previous CURL behavior kicks in."
A Collada camera will be added to the scenegraph as osg::CameraView. This allows the user to create a set of predefined camera viewpoints. I also added a new MatrixManipulator to osgGA called CameraViewSwitchManipulator and added usage of this to the osgviewer example. This manipulator allows switching between the predefined camera viewpoints. The current design limition I ran into is that a MatrixManipulator only manipulates the ViewMatrix, but for this particular manipulator I also want to update the projectionMatrix of the camera when switching to a new viewpoint. This is not implemented because I don't know what would be the best way to design it. Any ideas?
Furthermore Collada also supports orthographic camera's, where an osg::CameraView only supports a perspective camera. Would it be useful to create a CameraView with customizable optics for this?"
