05528abf25 From Chris Hanson: 
Spelling fixes in include/osg/LOD

   Negated priority in PagedLOD when using _rangeMode==PIXEL_SIZE_ON_SCREEN

   Added clampedPixelSize() methods to CullStack and CullingSet to return fabs()ed values.

   Changed LOD and PagedLOD ::traverse to use clampedPixelSize() methods.

e17ac7a8d9 Brede's changes for limited morphed vertex support. These changes allow 
a model with morphed vertecies to load correctly with LOD switches, but
does not implement the vertex morphing.

871cc70c32 From Ravi Mathur, added extension checks for point sprite support.

initialized to help with multi-thread and out of order context usage.

745834c329 Added triangle index functor to src/osgUtil/SphereSegment.cpp for computing 
the intersection between an indivual geometry and the sphere segment.

Converted the terrain in osgspheresegment to be an osg::Geometry based
drawable rather than a osg::ShapeDrawable/osg::HeightField one to make it
more practicle to use as a test for the new SphereSegment intersection code.

67e8e0b287 Added PolytopeVisitor to SphereSegment.cpp to help cull down to only drawables 
that intersect with the frustum of the SphereSegment. PolytopeVisitor may
eventually be pulled out to be more generally used along the lines of osgUtil::IntersectVisitor.
