Added kerning and line spacing (line height) to XTextFormatter

[Jonowa]

Hi community,

I've added some nice features to the XTextFormatter class. You can find them in my fork on:
https://github.com/Jonowa/PDFsharp

Usage:

var formatter = new XTextFormatter(gfx) {
    Kerning = 40,
    LineHeight = 12
};

I've already written an extension class for XGraphics for the PdfSharp V1.5. There you can pass html to the XGraphics-DrawText function. Maybe this could be a solution for adding more features to the XTextFormatter like changing font, size, colors, and many more.

Regards
Joerg

Hi!
Do not expect any enhancements to XTextFormatter to be ever included in the PDFsharp repository.
See line 11 of the source code: "/// Represents a very simple text formatter."

I added support for line heights and height calculation (page breaks) back in 2015.
