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.
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.
the names of the operations to be logged for stats purposes, or used when
do searches of the operation list. The keep member variable tells the graphics
thread run loop wether to remove the entry from the list once its been called.
the position of the emitter in the previous frame and the new position in the new
frame, the number of particles added also scales up to compensate for this movement.

This fixes some crashing issues I was having with certain FLT files that only had partial colour palettes
Which are typically found in older 14.x files and file converted through Polytrans or Deep exploration etc.
The code that grabs the color entries in ConvertFromFLT::visitColorPalette was assuming that there were full
palettes always coming in and stepping was out of bounds in certain cases (not all) and thus crashing with
access violations etc,
Although the normal from Creator is to have 1024 or 512 entries , this is not a really requirement of the format, just the way Creator creates its default palettes etc.
Code changed to look at the number of entries and use just those and fills in any missing entries with a default white colour"
"I add a new option in the HDR Reader.
The RAW option store the RGBE values into a Image, to use
this option you need to decode the RGBE value in the frag-
ment shader. Follow the cube map glsl decoder:
vec4 textureCubeRGBE( uniform samplerCube sampler, vec3 coords )
{
ivec4 rgbe = textureCube( sampler, coords ) * 255. + 0.5;
float e = rgbe.a - ( 128 + 8 );
return vec4( rgbe.rgb * exp2( e ), 1.0 );
}
This option is usefull for who have a outdate hardware like
FX cards and want to do cool things.
Finally this patch is need by a new HDR Rendering example
that I will put on the Wiki."
