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.

Change -r to -framerate, but either will work.
Change -s to -video_size, but either will work.

Also disable it by default since it looks currently buggy. The
usefulness of such library is mostly limited to backward compatibility
with very old devices.

We used to use 'framerate' or 'frame rate' randomly.

An input channel could have been previously set with another application, like
v4l2-ctl, so if no input channel is specified use the previosly selected one.

Allow to specify a filename where to put the filtergraph description.

This is useful to override limitations or glitches of particular shell

Add documentation for options draw_mouse, framerate, and video_size.

In particular, fix trac ticket #1314.

Improve rendering.

Create a dedicated options subchapter, rather than a subchapter for each
option.

This is more consistent with the rest of the docs. Also apply misc minor
fixes for improving rendering.
