    //=============================================================================
    // BrushBuilder: Base class of UnrealEd brush builders.
    //
    // Tips for writing brush builders:
    //
    // * Always validate the user-specified and call BadParameters function
    //   if anything is wrong, instead of actually building geometry.
    //   If you build an invalid brush due to bad user parameters, you'll
    //   cause an extraordinary amount of pain for the poor user.
    //
    // * When generating polygons with more than 3 vertices, BE SURE all the
    //   polygon's vertices are coplanar!  Out-of-plane polygons will cause
    //   geometry to be corrupted.
