//animation.Weighting = ...;
//Combined weightings usually should add up to 1.0
//A weighting of 0 means the animation has no effect, 1 has normal effect.
//Values outside the 0-1 range usually produces undesirable results.
//Note:
//Animations in xen are lossy compressed.
//For the model used here, the animation data is reduced from nearly 2mb
//down to around 200kb. (The model geometry is less than 300kb)
//The amount of compression change can be configured in the content's properties
//The 'Animation Compression Tolerance' value is a percentage
//The default is .5%. This means the animation will always be within .5%
//of the source. Setting this value to 0 will save a lossless animation.
