Draft: Add textured capsule source.

This implementation of the capsule adds texture coords for the capsule. The current implementation differs from the existing implementation by using a single sphere where the poles are aligned along the y-axis. The non-textured capsule is rotated and each hemisphere have their own poles parallel to the normal of the cylinder body. This implementation also deprecates the LatLongTessellation parameter as it generates the wireframe along the latitude and longitude of the hemisphere which are connected with triangles. This implementation is based on the vtkTexturedSphereSource.
