31 // Implementation for solid base class
32 //
33 // History:
34 //
35 // 06.12.02 V.Grichine, restored original conditions in ClipPolygon()
36 // 10.05.02 V.Grichine, ClipPolygon(): clip only other axis and limited voxels
37 // 15.04.02 V.Grichine, bug fixed in ClipPolygon(): clip only one axis
38 // 13.03.02 V.Grichine, cosmetics of voxel limit functions
39 // 15.11.00 D.Williams, V.Grichine, fix in CalculateClippedPolygonExtent()
40 // 10.07.95 P.Kent, Added == operator, solid Store entry
41 // 30.06.95 P.Kent, Created.
