/**jsdoc
* These are the properties of a <code>cube</code> {@link Overlays.OverlayType|OverlayType}.
* @typedef {object} Overlays.CubeProperties
*
* @property {string} type=cube - Has the value <code>"cube"</code>. <em>Read-only.</em>
* @property {Vec3Color} color=255,255,255 - The color of the overlay.
* @property {number} alpha=0.7 - The opacity of the overlay, <code>0.0</code> - <code>1.0</code>.
* @property {number} pulseMax=0 - The maximum value of the pulse multiplier.
* @property {number} pulseMin=0 - The minimum value of the pulse multiplier.
* @property {number} pulsePeriod=1 - The duration of the color and alpha pulse, in seconds. A pulse multiplier value goes from
* <code>pulseMin</code> to <code>pulseMax</code>, then <code>pulseMax</code> to <code>pulseMin</code> in one period.
* @property {number} alphaPulse=0 - If non-zero, the alpha of the overlay is pulsed: the alpha value is multiplied by the
* current pulse multiplier value each frame. If > 0 the pulse multiplier is applied in phase with the pulse period; if < 0
* the pulse multiplier is applied out of phase with the pulse period. (The magnitude of the property isn't otherwise
* used.)
* @property {number} colorPulse=0 - If non-zero, the color of the overlay is pulsed: the color value is multiplied by the
* current pulse multiplier value each frame. If > 0 the pulse multiplier is applied in phase with the pulse period; if < 0
* the pulse multiplier is applied out of phase with the pulse period. (The magnitude of the property isn't otherwise
* used.)
* @property {boolean} visible=true - If <code>true</code>, the overlay is rendered, otherwise it is not rendered.
*
* @property {string} name="" - A friendly name for the overlay.
* @property {Vec3} position - The position of the overlay center. Synonyms: <code>p1</code>, <code>point</code>, and
* <code>start</code>.
* @property {Vec3} localPosition - The local position of the overlay relative to its parent if the overlay has a
* <code>parentID</code> set, otherwise the same value as <code>position</code>.
* @property {Quat} rotation - The orientation of the overlay. Synonym: <code>orientation</code>.
* @property {Quat} localRotation - The orientation of the overlay relative to its parent if the overlay has a
* <code>parentID</code> set, otherwise the same value as <code>rotation</code>.
* @property {boolean} isSolid=false - Synonyms: <ode>solid</code>, <code>isFilled</code>, and <code>filled</code>.
* Antonyms: <code>isWire</code> and <code>wire</code>.
* @property {boolean} isDashedLine=false - If <code>true</code>, a dashed line is drawn on the overlay's edges. Synonym:
* <code>dashed</code>.
* @property {boolean} ignorePickIntersection=false - If <code>true</code>, picks ignore the overlay. <code>ignoreRayIntersection</code> is a synonym.
* @property {boolean} drawInFront=false - If <code>true</code>, the overlay is rendered in front of other overlays that don't
* have <code>drawInFront</code> set to <code>true</code>, and in front of entities.
* @property {boolean} grabbable=false - Signal to grabbing scripts whether or not this overlay can be grabbed.
* @property {Uuid} parentID=null - The avatar, entity, or overlay that the overlay is parented to.
* @property {number} parentJointIndex=65535 - Integer value specifying the skeleton joint that the overlay is attached to if
* <code>parentID</code> is an avatar skeleton. A value of <code>65535</code> means "no joint".
*
* @property {Vec3} dimensions - The dimensions of the overlay. Synonyms: <code>scale</code>, <code>size</code>.
