      Add Win32 GDI-based screen grabbing · 08909fb5
      Calvin Walton authored
      Based on original code by Christophe Gisquet in 2010, updated to work
      with current ffmpeg APIs.
      
      Supports grabbing a single window or an area of the screen, including
      support for multiple monitors (Windows does funky stuff with negative
      coordinates here).
      
      I've moved most of the configuration to AVOptions; the input file name
      is now only the string "desktop", or "title=<windowname>" to select a
      single window. The AVOptions are the same as x11grab where possible.
      
      Code has been added to support a "show_region" mode, like x11grab, which
      will draw a rectangle on the screen around the area being captured.
      
      Instead of duplicating code for paletted image handling, I make use of
      the GDI API's ability to output DIB (BMP) images, which can be run
      through ffmpeg's existing BMP decoder.
