// Class : VertexSlider
// 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.
