New methods osg::Geometry::containsDeprecatedData() and osg::Geometry::fixDeprecatedData() provide a means for converting geometries that still use the array indices and BIND_PER_PRIMITIVE across to complient
versions.
Cleaned up the rest of the OSG where use of array indices and BIND_PER_PRIMITIVE were accessed or used.
retessellatePolygons was applying the winding and boundary option.
Moved the gluTessProperty calls into beginTessellation().
There's a comment typo fix, removing an unused VertexPointList
typedef, and allocates one _tobj instead of one per tesellation.
Protections were added to check that _tobj was allocated in the few
remaining places it wasn't being checked.

On a side note, I would like to avoid the 'new Vec3d' in
Tessellator::addVertex for each call to
gluTessVertex(tess, location, data).
The RedBook leaves it ambiguous if the location pointer must
remain valid after gluTessVertex or not.

says that changing location is not safe, so being conservative, I'll
leave it as is, even though the Mesa GLU library copies the data not
the pointer, so it is currently safe."
changed extensions from .c to .cpp and got compiling as C files as part of the osg core library.
Updated and cleaned up the rest of the OSG to use the new internal GLU.
that has greater than unsigned short number of vertexes. An object
called vertexPtrToIndexMap contains vertexes and their indexes. This
std::map object can obviously hold a quantity that is greater than
unsigned short, however osg::DrawElementsUShort objects were being
created to reference these vertexes and their indexes.
osg::DrawElementsUShort can only hold indexes that are 16-bit
quantities.

proposed_patch_2\tessellator.cpp. This solution examines the size of
vertexPtrToIndexMap and selects 1 of 3 possible osg::DrawElements
objects: DrawElementsUByte, DrawElementsUShort, or DrawElementsUInt.
The main drawback of this particular solution is the code duplication.
However, the repair is straightforward."
