it conforms to the OpenFlight convention of euler angles. Added documentation
into Matrix and Quat to reflect this.
Added so test code to osgcube for stress testing memory allocation and deallocation.
Commented out the registering of app and cull callbacks in osghud.
the functionality clear given the name. This will break user code unfortunately
so please be away of the following mapping.
osg::Matrix::makeTrans(..)?\026 -> osg::Matrix::makeTranslate(..)
osg::Matrix::makeRot(..)?\026 -> osg::Matrix::makeRotate(..)
osg::Matrix::trans(..)?\026 -> osg::Matrix::translate(..)
osg::Quat::makeRot(..)?\026 -> osg::Quat::makeRotate(..)
Also updated the rest of the OSG distribution to use the new names, and
have removed the old deprecated Matrix methods too.
