AnimState functions: GetSymbolVariance, GetPercent and GetScale

[Tykvesh]

AnimState:GetSymbolVariance(symbol_name) - valid only for the caller sim

This function could return the variance of the symbol as a number. For example, each of these textures is a "variance":

 

 

 

 

AnimState:GetPercent()

It's already possible to get the percent of the current animation by calling this:

percent = AnimState:GetCurrentAnimationTime() / AnimState:GetCurrentAnimationLength()

but it's resulting in a bit.. inaccurate values, so it would be nice to be able to directly ask for the value.

 

AnimState:GetScale()

Currently it's impossible to inquire the scale from AnimState (Transform and AnimState scales are different things). Also, for some reason, AnimState scale doesn't affect the mouse detection hitbox.
