* 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.
* This typically means that the user hasn't checked correctly for SM6 feature
support before trying to upload DXIL shader, which will then result in
unpredictable behaviour or crashes on replay.
* During capture we detect this and flag it in the overlay text, and prevent
capturing. On capture load we fail to load if we detect such a PSO.
* Fortunately the extension doesn't add any functionality that can't be achieved
through the old bindings, it's just better decoupled.
* What we do is set up our own VAO attrib/binding tracking, and translate all
the functions (old and new style) into the equivalent modifications of that
state, then each time a change happens we flush out the attribs and bindings
using the old attrib functions.
* We also intercept the queries to the new bindings and return the right values,
so even if loading a capture that uses ARB_vertex_attrib_binding would work as
expected (as all the translation to old bindings happens under the emulation
layer).
* For pipelines using tessellation or containing a geometry shader we use
transform feedback to fetch the output of the vertex pipeline after these
stages.
* Screenshots and icons are updated to latest style
* Many out-dated references and mentions of support updated.
* Documentation added for new windows like resource inspector and
performance counter viewer, as well as new features like saving
bookmarks, resource names.
* Added documentation for Android support as well as OpenGL ES support.
