Special separator that performs locate highlighting.
This is a subclass of SoSeparator that redraws itself in a different color when the cursor is over the contents of the separator.
The redraw happens for that separator only and not the entire window (redraw along the handle event pick path) and in the front buffer, to efficiently track the mouse motion. The highlighted redraw overrides the emissive and/or diffuse color of the subgraph based on the field values in this node.
NOTE: when using SoLightModel::BASE_COLOR (to turn lighting off) only the diffuse color will be used to render objects, so EMISSIVE_DIFFUSE must be used for this node to have any effect.
Limitations:
The SceneOrbiter does not have such limitation.
To override the default mode (off), set environment variable IV_ALLOW_LOCATE_HIGHLIGHT to 1. This will allow locate highlighting to happen by default.

This will de-highlight the currently highlighted node if any.
this should be called when the cursor leaves a window or a mode changes happen which would prevent a highlighted node from receiving more mouse motion events. The GL render action used to render into that window needs to be passed to correctly un-highlight.
