This is supported by OpenGL, and on Vulkan with
VK_EXT_primitive_topology_list_restart. On Vulkan, all drivers are
known to support this even without
VK_EXT_primitive_topology_list_restart. On D3D, primitive restart is
only supported for strip topologies.
Previously, RenderDoc specifically disabled primitive restart for
non-strip topologies. In this change, that is no longer done. If the
app enables primitive restart, so will RenderDoc behave accordingly. It
would be the responsibility of the app to avoid primitive restart if the
API doesn't allow it.
* 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.
* These map more naturally to python tuples and are easier to wrap in and out.
* We also tidy up the FloatVecVal etc and standardise the members of
ShaderValue.
* In heavy D3D11 workloads the refcounting overhead especially during fast
binding changes was significant. Refactoring the refcounting to work on a
different model and deferring destruction of objects removes most of the
overhead.
* This helps catches cases where a discarded image is accidentally used and in
many cases may still have valid data. Particularly on Vulkan this is relevant
for DONT_CARE renderpass load and store ops.
* E.g. on D3D12 we can debug DXBC shaders but not DXIL shaders. On vulkan this
will allow us to have the UI work better when encountering shaders with
unsupported capabilities or extensions.
The assignment of logical identifiers is not guaranteed to match the
order of appearance in the shader bytecode. Adjusted D3D12_CBuffer_Zoo
to exercise this for testing.
* This doesn't test every edge case, but it is a simple smoke test that ensures
any format can at least get consistent accurate results out.
* Further work is needed to test the different failures, overdraws, primitive
IDs, and all the other specific checks in the history.
* The builtin is more directly useful but the signature index allows us to match
up inputs and outputs that don't have a builtin meaning (pure interpolators).
