Support MorphTargets in MeshDepthMaterial (#4662)
Cleaned up css3d sandbox example
Update points parser for VTK Loader

Some vtk files don't have float numbers in POINTS section.
They are int numbers. For example, parse wants:
0.0 1.5 2.0
But came:
0 1.5 2
In previos implementation parse pattern don't parse
This fix remove part after "." in number, and search will work
