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
Removed unnecessary and problematic immediate update when calling play on an Animation.  Update will accumulate the blend weights for the animation and we don't want it being done twice on any particular frame.
