04.02.24 <uploaded>

04.02.23

• VTBuilder: moved many options to the newly expanded View Options dialog, including new exposure of shadow casting as a shading option, with sun angle

04.02.18

04.02.13

• Massive re-architecture of the GIS classes: vtFeatures becomes vtFeatureSet with 4 derived classes by geometry type, proper handling of Polygons with holes,
• VTBuilder: large changes to match re-architecture: chg vtVegLayer to simply build off of vtRawLayer instead of re-implementing all the polygon functionality, rearchitected vtRawLayer to exploit vtFeatureSet by containment
