- Also replace GL/glew by vtk_glew in Core/RenderDetail
- Remove empty first line in those

- Remove RenderDetail::setTextureFilename() and co.
- Remove MeshModel::addTexture()
- Remove SurfaceMesh::assignTexture() and co.
- Use RenderDetail::addTexture()

Still need to assign texture in model?

The 3ds file loading and attachment  of VAO for the tangents
for 3DS file are working fine now.

Clean up and add static scene delegate.

Add tests to IO. Move variables, types and implementation
of utility methods to IOMeshDelagates base class.

Commented out the VegaVoumetricMesh test until after I debug the meshIO.

This data mapper allows you to map external data into the
vtkDataArray.
This in turn allows you to interface with vtk without
repacking the simulatordata.

Clean up and implement a pimpl VtkRenderer to hide
redering implementation.

Replace core::StdVector3d with std::vector<core::Vec3d>

because eigen 3d vector array is aligned
by default so no special allocator is needed. See core::StdVector3d
for more details.

Also renmamed many unseen sm* class names.
