Many users noticing that EMF DrawString is shifted horizontally in same cases.
It is caused by missing implementation of:
 - StringAlignment:
      Near: Alignment is to the left side of the layout rectangle
      Center: Specifies that alignment is centered
              between the origin and extent of the layout rectangle.
      Far:  Alignment is to the right side of the layout rectangle
 - Leading Margin: specifies the length of the space to add
   to the starting position of a string
 - trailing Margin: Length of the space to leave following a string.

With this path this missing parameters are implemented.
It was tested with document:
https://bugs.documentfoundation.org/attachment.cgi?id=131334

In following document StringAlignmentCenter and LeadingMargin is not set:

I make sure that there is no regression (the image should be displayed
as without the patch.
