Add support for math type equations.

When the user inserts a table in right-to-left mode, there is no ability to resize its rows/columns. The Table Properties dialog or the Document Ruler still can be used to resize the rows/columns of the Table.

When the document is in Web layout mode (with RadDocument.LayoutMode = "Flow"), and contains multiple sections with comments inside them, the comments are visualized on unexpected places outside of the comments pane, or one over another, hiding other comments.

Command that converts currently selected text to sentence case, lowercase, uppercase, capitalizes each word, or toggles case, while preserving the styling. A sample demonstrating how to add a custom implementation of a similar command is attached.

Include import and export in open XML - (<w:caps /> property in run properties) and in HTML (text-transform property).

A custom list has numbered list, which refer style and the style refer numbered list. If the second numbered list is not imported before importing the first the import will fail.

ArgumentException ("referenced document list does not exist."); is thrown and handled internally. It is caused by linked list styles. The style which refers other is imported before the referenced style. The RichTextBox expects that referred styles are imported before the styles that refer them.

Available in R3 2018 Official Release Version.

When floating image is added to empty table cell, it is positioned in a way that overlaps the table border. 

Implement support for exact table row height option. By using this option the text should be clipped when the table row height is lower than the height needed for the text to render. 
The current implementation supports only the at least option.

When floating image is all of the following: 
- is anchored to paragraph inside a table with negative offset.
- is with text wrapping "Behind text" or "In front of text"
it should be positioned outside of the table. Currently the image is always positioned fully inside the table.

Add support for importing/exporting macro-enabled document (*.dotm), while preserving the macro content.

Adding support for exporting font style as font tag. Android's TextView for example support styling only using tags.

When importing image with invalid ur/base64 encoded data the document won't be opened correctly and an exception will be thrown. Load default image instead of throwing exception and failing to open the document.

In paged layout mode, the caret becomes invisible when the document is scrolled to other page, so that the page with the caret goes out of the view port.

This behavior is also observed when editing, for example when inserting page break or section break.

Currently invalid attribute values, including invalid or empty values in CSS attributes in the 'style' attribute, could cause importing property with incorrect value, or NullReferenceException (the document cannot be imported).
Examples:
----------------------------------------------------------
<table width=”*”>
	<tr>
		<td>More Random Text</td>
	</tr>
</table>

The table is imported with 0 width. Instead the width should not be set.
----------------------------------------------------------
<table style="font-size:;">
	<tr>
		<td>More Random Text</td>
	</tr>
</table>

NullReferenceException is thrown.
----------------------------------------------------------

Workaround: replace the invalid values before import:
string importString = html.Replace("font-style: ;", "");

When the current SpanLayoutBox is split (for example by inserting space), the DocumentPosition created with trackDocumentChangeEvents option (with some of the constructor accepting the boolean 'trackDocumentChangeEvents' parameter) jumps back with two symbols.

We've run into the following problem with the RadDocumentEditor:

1. Turn on bold
2. Type some characters.
3. Turn off bold.
4. Insert some text using the Insert method in Telerik.Windows.Documents.Model.RadDocumentEditor.

The inserted text is bold; it should ​have no formatting.

Tab stops with visible tab leader (dot, hyphen, underscore) are not exported to PDF.

Steps to reproduce:
- Start with empty document
- In Paragraph Properties dialog, choose Tabs
- In Tab dialog, enter Tab stop position = 2, Leader = underscore, and press Set. Press OK
- Add a word, press Tab, add another word
- Export the text to PDF

Expected: the words are separated with underscores in the exported PDF.
Actual: the words are separated with blank space in the exported PDF.

When hyperlink is within another annotation so that the outer annotation touches the hyperlink annotation, editing the hyperlink with Insert Hyperlink dialog moves parts of the text of the hyperlink, or the outer annotation. Reproducible with Comments and Bookmarks.

Steps to reproduce:

Variant 1:
1. Insert Hyperlink
2. Enter some text after the Hyperlink (eg. ' Test')
3. Select the Hyperlink and the text and Insert Comment
4. Edit the target of the hyperlink with the Insert Hyperlink Dialog

Expected: The text is not changed.
Actual: Space between Hyperlink and the text is moved before the Hyperlink

------------------------------------------------

Variant 2:

1. Insert three words and make the middle hyperlink.
2. Insert comment or bookmark over the hyperlink
3. Edit the target of the hyperlink with the Insert Hyperlink Dialog

Expected: Annotations are not reordered
Actual: Comment (bookmark) annotations change their places.

The unit that is used by default is px. Allow modification to the default unit, say pt.
