* When searching for the start of a range of instructions mapped to a single
line when stepping backwards, we need to ignore instructions that don't have
any debug info because they will look like a 'different' smaller stack.
This change exposes the
VkPipelineViewportDepthClipControlCreateInfoEXT::negativeOneToOne
pipeline state in the UI. While not a per-viewport state, this state is
output alongside viewport information.
If the extension is not used, or if this flag is false, [0, 1] is shown
as the depth clip range. If the flag is true, [-1, 1] is shown.
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.
* This helps those who have chosen the dark theme where rich resource text uses
the default window text colour assuming it's a contrasting colour against the
background (except when highlighted).
* We need to calculate the fixed data length properly even when there is no
repeated data, so that pagination doesn't kick in on the data that is needed
for the fixed region.
* We store the compiler used (when known) in shader debug info and use that to
select the compiler for editing as even higher priority than the default for a
given language/encoding combination.
* We also ensure that for known tools we add the input and output parameters
last, after any custom parameters, so that they are always present regardless
of what the user puts in.
* This allows us to more accurately display those that have been modified since
the last step, when a source-level step covers multiple instruction-level
steps.
* We also do our own sorting of source variables based on how recently they were
updated. This applies in both directions, so stepping backwards and
'reversing' a variable change will also count as a recent update.
* Since the source vars data doesn't change for a given instruction, we can pre-
calculate it and save time on re-calculating per-state.
* Note callstack *can* change per-state on SPIR-V where the same instruction can
be reached by different flow paths, so the callstack remains part of the per-
state data.
* We can't debug geometry shaders but we can scroll to them, as long as we have
the primitive. We can't differentiate instances currently without passing that
data through from the VS (and through tessellation, if it exists).
* This also disables the debug and goto buttons for printfs from shader stages
that don't support those operations.
* The GL clip origin when changed from lower left to upper left will also invert
the face culling sense. This is deliberate to counteract the fact that
otherwise CW wound triangles would be CCW wound, so the flip means that if
GL_CCW is the front face state and back faces are culled, then visibly CCW
wound triangles will be culled.
