-/**
- * \ingroup rtltmap
- * \ref RtLtMapIlluminateSampleCallBack is the callback to be called, from
- * within \ref RtLtMapIlluminate, for groups of samples in the objects
- * currently being illuminated.
- *
- * For lightmapped objects, samples are grouped on a per-polygon basis and
- * for vertex-lit objects, samples are grouped on a per-object basis (see
- * \ref RtLtMapObjectFlags).
- *
- * This callback will receive an array of color values to fill in, each
- * representing one sample in the current object - this may correspond to
- * a texel in the current object's lightmap or the prelight color of a
- * vertex, depending on whether the object is lightmapped and/or vertex-lit.
- * It will receive positions (in world-space) for each sample and the normal
- * vector (again, in world-space) of each sample (normals are interpolated
- * across polygons for non-flat-shaded materials. See \ref RtLtMapMaterialFlags).
- * For lightmap samples (not vertex-lighting samples), it will receive
- * barycentric coordinates within the current polygon.  It will also receive
- * a list of RpLights affecting the current object.
- *
- * The barycentric coordinates may be used, for example, to allow a callback
- * to easily import existing lighting data (e.g from previously generated
- * lightmaps in a different format, or from an art package with lighting
- * functionality).
- *
- * NOTE: The alpha channel of the RwRGBA results array must NOT be modified.
- * These values are used internally and their modification may result in
- * unwanted visual artifacts in the resulting lighting solution.
- *
- * The default RtLtMapIlluminateSampleCallBacks supplied with RtLtMap is
- * \ref RtLtMapDefaultSampleCallBack. This callback performs point and area
- * lighting (the area lights use are those passed to \ref RtLtMapIlluminate).
- *
- * \param  results          A pointer to an array of \ref RwRGBA sample color values
- * \param  samplePositions  A pointer to an array of \ref RwV3d values specifying the
- *                          world-space positions of each of the samples in the results array
- * \param  baryCoords       A pointer to an array of \ref RwV3d values specifying the

- *                          each of the samples in the results array

- * \ingroup rtltmap
- * \ref RtLtMapIlluminateVisCallBack is the callback to be called, from

- * sample and a light.
- *
- * This callback is called for all samples in the current
- * \ref RtLtMapLightingSession and for each light source which may
- * potentially affect each of those samples (this may not be all the
- * lights in the scene, as some hierarchical culling is performed).
- * Each sample may represent a texel in the current object's lightmap
- * or the prelight color of a vertex, depending on whether the object
- * is lightmapped and/or vertex-lit (see \ref RtLtMapObjectFlags).
- *
- * The callback will receive a pointer to the world of the current
- * \ref RtLtMapLightingSession (this may be used to perform intersection
- * tests), the world-space position of the sample, the world-space
- * position of the light, a pointer to a light and a pointer to an
- * \ref RwRGBAReal result value.
- *
- * If the light pointer is NULL, this means that the current light
- * is an area light (as opposed to an \ref RpLight), of an internal
- * format. The area lights use are those passed to \ref RtLtMapIlluminate.
- *
- * The callback should return FALSE to signify that the light is wholly
- * occluded w.r.t the sample position, otherwise it should return TRUE.
- * Partial degrees of (color-frequency-dependent) occlusion may be
- * expressed by modifying the RwRGBAReal value. This defaults to bright
- * white but may be reduced to signify that the light from the light
- * source should be attenuated. This could be used to take into account
- * light-filtering objects in the scene (such as colored glass or fog).
- *
- * The default RtLtMapIlluminateVisCallBack supplied with RtLtMap is
- * \ref RtLtMapDefaultVisCallBack. This callback performs visibility
- * tests using the line-intersection tests from \ref rtintersection. It tests
- * for occlusion by RpWorldSectors and RpAtomics and it respects the
- * relevant \ref RtLtMapObjectFlags and \ref RtLtMapMaterialFlags but it
- * does not filter light; visibility is determined to be either one or zero.
- *

- * \param  result     An RwRGBAReal value to attentuate this light's

- * \param  samplePos  The world-space positiuon of the sample
- * \param  lightPos   The world-space positiuon of the light
- * \param  light      A pointer to the light (NULL if it is an are light)
- *

- * \ingroup rtltmap
- * \ref RtLtMapIlluminateProgressCallBack is the callback to be called, from
- * within \ref RtLtMapIlluminate, to allow a user to track lighting progress.
- *
- * The progress callback will be called at several stages during lighting,
- * with a different 'message' parameter value used at each stage (see
- * \ref RtLtMapProgressMessage). It will be called at the very start of
- * lighting (for a given \ref RtLtMapLightingSession), before any samples
- * are lit. It will also be called at the very end of lighting, after all
- * samples have been lit. It will be called before and after each lighting
- * 'slice' (see \ref RtLtMapIlluminate) and also after each group of
- * samples have been lit.
- *
- * For lightmapped objects, samples are grouped on a per-polygon basis and
- * for vertex-lit objects, samples are grouped on a per-object basis (see
- * \ref RtLtMapObjectFlags).
- *
- * The progress callback will receive a RwReal value specifying the percentage
- * of samples already lit in the current \ref RtLtMapLightingSession (see
- * \ref RtLtMapLightingSessionGetNumSamples).
- *
- * By returning FALSE, the progress callback may cause early termination of
- * the current lighting 'slice' (this may be used, for example, to keep
- * the time spent lighting each slice fairly constant).
- *
- * There is no default progress callback supplied with RtLtMap.
