Remarks
The EnvelopeBuilderEx methods can be called on any thread.

An Envelope is an axis-aligned box described by the coordinates of the lower left corner and the coordinates of the upper right corner.

Use the EnvelopeBuilderEx class to to create and/or modify an Envelope shape. An Envelope is based upon the parent Geometry class. The Geometry class is immutable which means that you can not change its shape once it is created. Hence, the EnvelopeBuilderEx provides the way to make changes when working with an Envelope. Use the ToGeometry method to get the Envelope geometry from the builder.
