ScalarsToColors defines the interface to map a scalar value to a color, and provides a default implementation of the mapping functionaltity, with colors ranging from black to white across the min - max scalar range.

| bool | getThreadSafeRefUnref () const |
| | Get whether a mutex is used to ensure ref() and unref() are thread safe.

| int | ref () const |
| | Increment the reference count by one, indicating that this object has another pointer which is referencing it.

| |
| int | unref_nodelete () const |
| | Decrement the reference count by one, indicating that a pointer to this object is no longer referencing it.
|
| |
| int | referenceCount () const |
| | Return the number of pointers currently referencing this object.
|
| |
| ObserverSet * | getObserverSet () const |
| | Get the ObserverSet if one is attached, otherwise return NULL.
|
| |
| ObserverSet * | getOrCreateObserverSet () const |
| | Get the ObserverSet if one is attached, otherwise create an ObserverSet, attach it, then return this newly created ObserverSet.
