Detailed Description

GLUtilTesselator transform OutlineShapes to triangles using glutess2.

• The triangle's vertices are added to a given GLFloatArrayDataServer
• If selected by flags, normals are added to the same GLFloatArrayDataServer (interleaved)
• The triangle (strip, fan or plain) segments are captured via GLUtilTesselator::Segment and returned by the GLUtilTesselator::tesselate() command
• Utilizes glutess2 in single precision float
