Physical Document Content Margins

Hi,

I'm sure this is easily possible and I'm looking in the wrong place, but I want to be able to "indent" [margin] the document content, that is the text within the scrollable region the syntax editor has.

I've used Snoop to get a look at the visual tree and played with setting on the margin at various levels and the following gets just what I need:

SyntaxEditor

     AdornerDecorator

          EditorViewHost

               EditorView

                    ElementChrome

                         ContentPresenter

                              Grid

                                   Grid <- set margin of 5 here perfectly indents the text content and keeps line/selection margin content inline but doesn't move scrollbars of the overall control

Is it possible to do something like this? I hope I've explained properly.

Thanks,

Simon
