/* Class for storing set of display parameters.
 *
 * The interface sort of emulates map string->string (which is not handled by yade-serialization).
 *
 * The "keys" (called displayTypes) are intended to be "OpenGLRenderer" or "GLViewer" (and perhaps other).
 * The "values" are intended to be XML representation of display parameters, obtained either by yade-serialization
 * with OpenGLRenderer and saveStateToStream with QGLViewer (and GLViewer).
