Updated Node to include contribution of point light spheres into node bounding volume computation.
Fixed an issue where multiple samplers pointing to the same texture would share the same state instead of using sampler-specific filter and wrap state.
Removed Texture::setFilter and Texture::setWrapMode functions, since the equivalent functions on Texture::Sampler should be used instead.
