WordsProcessing: Add support for TextDirection of table cell when exporting to pdf

The .bin extension represents a binary file format which can contain images as well. When a document containing such an image is imported and exported using WordsProcessing, the image is lost and the default 'no-image' placeholder is used in its place.

Add support for manual calculation option, which allows not to recalculate all the formulas on value change, but on manual request. 

MS Excel supports this feature in Formulas -> Calculation -> Calculation Options, with the following options: Automatic, Automatic Except for Data Tables, Manual.

Add support for import and export of floating tables.

When writing a RadFixedPage containing widgets using the PdfPageStreamWriter.WriteContent() method an exception is thrown.

The exception: System.ArgumentNullException: 'Value cannot be null. Parameter name: context'

From the PDF Specification: "An ink annotation represents a freehand “scribble” composed of one or more disjoint paths. When opened, it displays a pop-up window containing the text of the associated note."

Endless loop while the PDF exporter splits a block with an image. This image size is close to the page size but cannot fit in this case.

Shapes are currently skipped when exporting document content to HTML. Add logic to preserve them.

In addition to the fast document generation, the SpreadStreamProcessing can be adapted to import documents significantly faster than SpreadProcessing.

Add support for shapes, and especially for shapes with textual content. 
In OOXML, shapes are represented by the wps:wsp element, and shapes with textual content by <wps:txbx>, <w:txbxContent>.
Such shape can be added to a Word document using the Insert -> Text -> Text Box -> Draw Text Box, or through a shape's context menu -> Add Text.

Do not confuse these shapes with Text/Rich Text content controls (see https://feedback.telerik.com/Project/184/Feedback/Details/190057 )

This attribute is needed to ensure the text values entered by users will appear in the same way as they inserted them. However, there are customers preferring to decrease the file size and skip this attribute. Expose a setting to allow them to achieve that.

Hello,

we would like to have the capability to create a chart in excel export using Telerik.Documents.Spreadsheet

Currently RadFixedDocumentInfo is used only for export of Author, Title and Description document metadata properties. This should be extended to support custom properties. We should also implement the import of RadFixedDocumentInfo.

Add support for importing shapes from RTF

 Add support for the background tag: html - CSS color vs. background-color vs. background? - Stack Overflow

Add support for custom attributes from the Kendo editor. For example "k-colgroup-data".

PDF/A-1a is with conformance level A (for "accessibility"), and must adhere to all of the requirements of the PDF Reference as modified by the ISO 19005 specification. 

It requires structural and semantic properties to be preserved. Level 1a uses “Tagged PDF” and Unicode character maps to preserve the document's logical structure and content text stream in natural reading order. 

The following features are used:
- Language specification
- Hierarchical document structure
- Tagged text spans and descriptive text for images and symbols
- Character mappings to Unicode

The purpose is to improve accessibility and make the content accessible for screen readers.

Currently, the following text filters are not supported in the model:

• begins with
• does not begin with
• ends with
• does not end with
• contains
• does not contain

Currently, when users need to add content to an existing page that is rotated, they should manually calculate the positions of the new content if they need to align it with the appearance of the page. Add API allowing them to easily transform the position respecting the top left edge of the page after its rotation.

When exporting, an option of how to create the PDF bookmarks should be provided:
- Using the RadFlowDocument bookmarks
- Using document Headings
