Added support for Window Polygon and Crossing Polygon selection.
Added new methods to 'vdcanvas' object:
GetEntitiesInWindowPolygon - A window polygon selection that returns an array of vdraw entities that lie entirely inside a specified closed polygon. Even if a small part of an entity lies outside the polygon, the entity is ignored.
GetEntitiesFromPolygon - A crossing polygon selection that returns an array of vdraw entities that cross a specified closed polygon. Even if a small part of an entity lies inside the polygon, it is added in the array.
Added support for Microsoft .NET Core 6.
New License Management - Added a new command-line application called vdlic.exe, which will help you create a license file that should be distributed with your application.
Units for Length are now always on inches unless otherwise specified when exporting SKP files.
