Rename 'draw' or 'drawcall' to action

Browse Source 
* There's not a good accepted terminology for this kind of event, and for
  historical reasons 'drawcall' has been the accepted term, even though
  that can be quite confusing when a dispatch or a copy is a 'drawcall'.
* This is particularly highlighted by the event browser filters where
  $draw() includes draws and dispatches, but $dispatch() only includes
  dispatches, it's hard to intuitively understand why $draw() matches all
  of these calls.
* As a result we've defined the term 'action' to cover these types of
  events in the same way that we defined 'event' in the first place to
  mean a single atomic API call.

Save a texture to disk
======================
In this example we will find a particular drawcall, and save the color output to disk as an image file.
In this example we will find a particular action, and save the color output to disk as an image file.
To begin with, so that we have an interesting drawcall selected we iterate over the list of draws finding the drawcall with the highest vertex count. For more on how to iterate through a capture's list of drawcalls, see :doc:`iter_draws`.

Once we have set the drawcall we want as the current event, we can configure the texture save operation. To do this we create a :py:class:`~renderdoc.TextureSave` object. The properties of the object determine how the texture will be mapped to an image file to be saved to disk.

At minimum you need to select a file format, and we'll try a few - :py:attr:`~renderdoc.FileType.JPG`, :py:attr:`~renderdoc.FileType.HDR`, :py:attr:`~renderdoc.FileType.PNG`, and :py:attr:`~renderdoc.FileType.DDS`.
