With the current implementation when exporting a Stitching function all the containing functions are exported as Sampled functions even if they originally have been imported as Exponential interpolation functions, which leads to an increase in the size of the document.

More information can be found in the PDF Specification.

The XlsxPartNames class expects a strict name for reading the comments parts:

public const string CommentsPartName = @"/xl/comments{0}.xml";

However, some third-party tools may change the name to GemComments.xml for example. 

MS Excel recognizes this naming for the comments part. It would be nice to provide such functionality in RadSpreadProcessing.

Add support for VML shapes.

Related: Add support for Shape Group.

Shape Group is used to collect shapes and groups so they can be positioned and transformed as a single unit. A group contains group, shapetype, shape, pre-defined shape - arc, curve, image, line, oval, polyline, rect, roundrect - and lock elements.

When the object is serialized out as XML, its qualified name is v:group.
