Prior to 7.4, occt had a 'using namespace std' in a header file that
was polluting dependent projects. They have since fixed it and so these
changes are required.
Second text alignment is wrong when "--alignment" specified.
3D text radius is too small, only SCREEN_COORDS can be seen.
Text position should multiply radius.
Following statement will never set OpenSceneGraph_osgText_FOUND to TRUE:
```
FIND_PACKAGE(OpenSceneGraph REQUIRED COMPONENTS osgViewer osgText CONFIG)
```
It cause cmake failure, the error message is confusing:
```
Found package configuration file:
/usr/local/osg/gl2/lib/cmake/OpenSceneGraph/OpenSceneGraphConfig.cmake
but it set OpenSceneGraph_FOUND to FALSE so package "OpenSceneGraph" is
considered to be NOT FOUND.
```
I know one doesn't need to add osgText after osgViewer, but it should
not cause an error with confusing message.
As xine is not used anymore, there is no plugin in charge of loading
video files, and osgmovie and other programs are not able to open
them.
If ffmpeg is present, it is registered for opening video files.
Replace operators for implicit type conversion by explicit data() method to
access implementation pointer and subscript operator to access element by
index just like in std::vector.
