title: Create a high-resolution device-context
body: <p>In order to solve problems with rendering of RichText, for which there is no other elegant alternative, I require providing a high-resolution device-context (e.g. 600 dpi) to the text-service interface.</p>
  
  <p>Is there a way to create such a device-context? I do not want to rely on an installed printer driver or something similar.</p>
