SoFloatElement is an abstract base class for elements that consists of a single float value.
This is the superclass of elements where the new element data replaces the old data, and where the data the element stores is a simple single precision floating point value.
This element is like a convenient light-weight version of the SoReplacedElement. It differs from the SoReplacedElement in that the set() and get() methods are already implemented, since it is known that subclasses will still contain just a single float value.

This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.
Reimplemented from SoElement.
Reimplemented in SoTextureScaleQualityElement, SoGLPointSizeElement, SoComplexityElement, SoCreaseAngleElement, SoDecimationPercentageElement, SoFocalDistanceElement, SoFontSizeElement, SoGLLineWidthElement, SoLineWidthElement, SoListenerGainElement, SoPointSizeElement, and SoTextureQualityElement.

This function returns TRUE
is the element matches another element (of the same class), with respect to cache validity.
If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function.
Implements SoElement.

This function creates a copy of the element that contains enough information to enable the matches() function to work.
