/**
* Returns a position in model coordinates relative to eye taking into

* <p>
* This uses standard position attributes, <code>position3DHigh</code>,
* <code>position3DLow</code>, <code>position2DHigh</code>, and <code>position2DLow</code>,
* and should be used when writing a vertex shader for an {@link Appearance}.

*
* @returns {vec4} The position relative to eye.

* @example
* vec4 p = czm_computePosition();
* v_positionEC = (czm_modelViewRelativeToEye * p).xyz;
* gl_Position = czm_modelViewProjectionRelativeToEye * p;
*
* @see czm_translateRelativeToEye
