Crowd sourcing Prior-art search

The U.S. Department of Commerce’s United States Patent and Trademark Office (USPTO) encourages subject-matter experts to take advantage of a new rule implemented under the Leahy-Smith America Invents Act (AIA) that allows third parties to submit relevant materials to patent examiners in any given examination. Submission of proposed prior art helps examiners determine whether the innovation in the application is patentable. 
To give effect to this provision, on Sept. 20, 2012, the USPTO partnered with Stack Exchange (a popular question/answer tech website) and Google to create Like other Stack Exchange websites, is formatted in a question/answer style in which citizen volunteers and other interested parties ask about patent applications (and patents) they think are suspicious. In turn, the community reviews the questions, proposes prior art solutions and votes up/down posted prior art to rate examples people find. The USPTO provides a system for submission of the prior art, while Google provides an algorithmic search utility to help uncover references.
Case: Scaling based on pixel density (Microsoft)- rejected by USPTO based on prior art by Ask patent community.
TITLE: Scale factors for visual presentations
  • Publication NumberUS 20130063492 A1
  • App Number13/230445
  • Assignee: Microsoft Corporation
  • Prior Art Cutoff Date: Prior Art predating Sept 12, 2011
  • Availability for Challenge: Open Until at least Sept 14, 2013
Summary: This application generates and display graphical elements based on pixel density. The invention selects a scale factor from a scale factor set that is within the range of the pixel density.
Claim 1 requires, among other things:
A method of generating, using a device having a processor, a presentation comprising elements to be displayed on a display component, the method comprising:
  • executing on the processor instructions configured to:
    • identify a pixel density of the display component;
    • for respective elements of the presentation:
      • from a scale factor set, select a scale factor having a pixel density range including the pixel density of the display component; and
      • request the element to generate a scaled representation using the scale factor; and
    • generate the presentation comprising the scaled representations of the elements.
QUESTION - Have you seen anything that was published before 09/12/2011 that discusses (1) scale factor; (2) scale factor set; and (3) pixel density range in the manner described in claim 1?
Best Answer: "Writing DPI-Aware Win32 Applications", an article by Ryan Haveson and Ken Sykes, published by Microsoft and dated September 2008.
