* We change to use VarType instead of CompType for signature parameters which
allows us to represent different types of variables beyond just
unsigned/signed integer and float.
D3D12Pipe now stores an array of root elements, each one corresponding
to a root element or range in the root signature. Migrated usage in the
D3D12 pipeline state viewer and PipeState retrieval of resources.
Restricted number of resource array textures displayed in the texture
viewer to prevent app hangs.
* This allows persistent config storage and registering tweak variables that
works independent of the UI's configuration.
* Config vars can be debug only, which means they will be compiled out in stable
version releases. This allows for debug-logging tweaks that are available in
all builds (including nightly builds) for diagnostic purposes, but have zero
overhead in stable releases.
* Variables have a loose hierarchy defined with _ or . to separate nodes.
* We instead always have 3rdparty/ in the relevant include search paths and rely
on that. Each library still has its own unique base dir within 3rdparty to
clarify where the include is coming from.
* This lets the user override the default application font.
* Unfortunately Qt seems to behave inconsistently with font scaling from the
system, so we take the font size initially from QApplication::font() (which
doesn't always pick up the font size) and scale from there. While this might
cause some font scaling to be lost it does mean at least we have a consistent
scale, as otherwise you get some text scaling and others not.
* The ShaderDebugTrace now only sets up the initial state of an opaque
ShaderDebugger handle.
* This handle can then be passed to a new function - ContinueDebug - to
iteratively return N more states. The number of states is implementation
defined and may be a fixed number or it may run for a fixed time.
* The states themselves no longer contain a complete snapshot of all variables,
but instead only the changed variables for that iteration. The changes are
stored as before and after value to make it easier to step forwards and
backwards (only the ShaderDebugState is needed to move forward or backwards,
you don't have to search back for the last set value of a variable to 'undo' a
change).
* The shader viewer shouldn't handle specifics of D3D bytecode, instead it now
works generally with whatever the debug and source variables are.
* VarType::Unknown is used for D3D registers which are typeless.
* Moving away from 'registers' explicitly being stored, we now have a single
variable array where the shader representation is responsible for allocating
it.
* In DXBC we calculate the number of each type of mutable variable (temps,
indexable temps, and outputs) and assign slots linearly.
* We also update some naming - high-level variables aren't "locals" since they
could be globals too, and debugging variables aren't "registers" but simply
the variables we use for debugging which may be more complex than float4 for
other APIs.
* The local variable matching by string name is unnecessary for this change
but will be more useful in future after further refactors where there isn't
a single list of variables to index into at the upper level.
* It's required for replay applications to call InitialiseReplay() before doing
any work, and to call ShutdownReplay() once they're finished.
* This lets us do more heavyweight shutdown work before global destructors are
being invoked and the RenderDoc instance is being destroyed.
* Anything that needs to be shut down during capture still has to happen in
RenderDoc::~RenderDoc since we obviously can't get the application to call a
shutdown function in that situation.
