* We also add the ability to toggle on/off the replacement being active without
needing to intentionally add a compile error (and this also makes it more
explicitly clear when the shader replacement is enabled or not. This could be
useful for quick A/B testing between the edited version and the original.
* We still need to handle multiple elements in the root of a struct specially by
commenting out the fixed members, but the final element needs to go through
the normal DeclareStruct() path to handle things like per-column padding in
matrices etc.
* The UI will become non-functional and the backend will be replaced with a do-
nothing one that keeps things alive without needing error bulletproofing
everywhere in the real backend.
* We split stepping for source debugging into step over/into/out depending on
how it handles function calls. Step Into is the same behaviour as before - it
steps to the next source line executed regardless of if it's inside a function
call. Step Over is similar but will not enter function calls. We define that
as the callstack growing (so staying the same or shrinking - returning from a
function - is OK), and this is as accurate as the underlying debug
information. Step Out will run until the callstack shrinks, i.e. returning
from a function.
* This is a slight behaviour change of keyboard shortcuts - F10 was effectively
doing step into and will now step over. F11 will step into which is the old
behaviour.
* All these variants have backwards versions, and to remain consistent we keep
the shift modifier as forwards/backwards. This differs from visal studio where
step out is shift-F10.
* The seems like the best balance - using any other variant would likely confuse
muscle memory of anyone used to visual studio (where these shortcuts are
intended to mimick), if only because F10 would be step into whether or not F11
is used for step over or some other key which would likely be even more
confusing either way. Trying to twist to use Shift-F10 for step out would be
inconsistent with the other backwards running operations and likely cause more
confusion than it saves in matching VS's shortcuts exactly. Also an accidental
Shift-F10 is not too destructive, the user can realise it didn't Step Out
forwards, and press Ctrl-F10 or look up the button.
* The hope is that most likely people doing source debugging and familiar with
these keys expect F10 to step over, so the previous behaviour was unexpected
but easy to work around, and that changing the meaning of the key won't
disrupt them. Or at least the disruption is less than other alternatives.
* This is a deliberate break of compatibility since the field is now often
empty, for non-markers. This means code will get a more explicit error when
the name is being referenced, so it can be updated to fetch the name it needs
as needed.
* 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.
* The current filter is preserved across runs even if it's not explicitly saved.
Saved filters are only updated with an explicit save - loading a filter then
making a change just cahnges the current scratch filter, it doesn't update the
saved filter until the user explicitly saves it.
* Fake markers now need a real event ID. We don't want to have to remap all
events in a capture between UI and replay driver, so instead we assign non-
contiguous events above the normal range and expect the UI to handle it.
* This option (in spite of large warnings) continues to be a pitfall for new and
experienced users alike, trying to use process injection without good reason
and getting into trouble when it breaks.
