title: Proper way to convert an Enhanced Metafile to a Windows Metafile without pixel rounding
body: <p>When I convert an Enhanced Metafile (constructed via GDI+ in C#) into an old-style Windows Metafile, the results are very rough, apparently because coordinates are being rounded to the nearest screen pixel.  I see this if I convert either via </p>
  
  <p>GetWinMetaFileBits(emfh, bits_l, bits, MM_ANISOTROPIC, GetDC(0));</p>
  
  <p>or using GDI+'s Metafile::EmfToWmfBits.  The culprit is presumably the screen DC being used.  <a href="http://www.powerbasic.com/support/pbforums/showthread.php?t=21530" rel="nofollow">This posting</a> suggests using a printer DC, which works for me, but obviously will not work if the user has no printers installed.  Is there a better way?  I have considered creating a high-resolution in-memory DC for the purpose, but I can find no proper documentation for doing so, and I also worry about the RAM used.</p>
