Detailed Description

This is an abstract base class that retains some slider value, which is a linear value that typically ranges from 0.0 to 1.0, and is used to control the animation of morphs (blend shapes).

It is similar to VertexTransform, which keeps a full 4x4 transform matrix, but the VertexSlider only keeps a single float value.
