[x3d-public] HAnim Winter and Spring: some progress

[Andreas Plesch]

I processed the Leif.x3d to remove the white boxes, filter out
skincoordindices with very small weights, and limit the numerical
precision of floating point numbers (it looks like the original source
had four or five digits after the decimal point):

This includes the processing script commented out. Using an
appropriate numerical precision reduces the file size almost by half.

is the original xml conversion with a running processing script which
logs to the console, for playing around and completeness. The script
is executed and after pressing Update
