Looking good! I have mostly style comments. I'm not seeing why we need to modify SkDevice.h/cpp. Can all the changes go into SkPDFDevice.h/cpp? http://codereview.appspot.com/4657087/diff/5001/include/core/SkDevice.h File include/core/SkDevice.h (right): http://codereview.appspot.com/4657087/diff/5001/include/core/SkDevice.h#newco... include/core/SkDevice.h:235: MARGIN_DA, The enum values should be named kMargin_DrawingArea and kContent_DrawingArea.

What is the background on why we need a new virtual on device? Is it of any interest to raster or gpu?

I reformatted some of the comments and added a TODO in SkPDFDevice::setDrawingArea. Committed as revision 1843. You can close this issue now.
