Bug 1479234 - Introduce a generic function to get an animation value on the compositor. r=boris,froydnj On the compositor we store animation values in a hash table and the hash is the compositor animation id which is a unique id for each property respectively. So we can get the corresponding animation value for the given property. In this patch there are lots of duplicated code, but they will be removed in the next patch. MozReview-Commit-ID: 7EboVcculcg
