* Previously if a handle was reused, and then a stale descriptor referencing the
old handle was removed it would remove the *new* object from the list of
referenced resources. This could cause a resource to be not included in a
capture if nothing else added a new reference.
* On all APIs structs are aligned up to 16-byte alignment, and on D3D as with
arrays then elements coming after the struct can be packed into the padding
after the last struct element.
* These tests ensure that texture rendering works correctly for all different
types of texture types, and for all formats, across different APIs, including
across a remote-proxy connection.
* Subresource handling is more consistent - we pass around a struct now that
contains the array slice, mip level, and sample. We remove the concept of
'MSAA textures count samples as extra slices within the real slices' and
internalise that completely. This also means we have a consistent set
everywhere that we need to refer to a subresource.
* Functions that used to be in the ReplayOutput and use a couple of implicit
parameters from the texture viewer configuration are now in the
ReplayController and take them explicitly. This includes GetMinMax,
GetHistogram, and PickPixel.
* Since these functions aren't ReplayOutput relative, if you want to decode the
custom shader texture or the overlay texture you need to pass that ID
directly.
* We also make sure that if we go back to a previous event to debug, that we
look up the right output corresponding to where it's bound there (since it
might be bound to a different slot).
* Even if a function isn't passed a global binding array as a parameter, we
still need to patch it in order to find any accesses it makes directly to
global resources just as we do in the entry point.
* Instead of patching e.g. PRESENT to GENERAL early, we keep the 'real' layout
even if that's UNDEFINED or PRESENT or whatever. We then do a last-second
patchup whenever we're actually transitioning images in vulkan itself, to set
the right layout.
* This requires us to do the patching in a few more places - anywhere like
texture rendering or initial states where we want to go from current state ->
custom state -> back to current state.
* This also allows us to more gracefully handle PREINITIALIZED image layouts. We
internally promote them to GENERAL as soon as possible, but keep them around
as PREINITIALIZED for display.
* We are really looking for persistent memory leaks here not fluctuations in
memory use. There are too many false positives from memory usage increasing up
high part-way through the iterations and then reducing down for the final
iteration, which could be many lazy or deferred things running and completing
over time.
* This is better than testing by platform/platform version, because we can check
specifically for extensions and avoid running a test we know will fail because
extensions aren't supported.
* This is required because we add MAP_READ_BIT and the spec doesn't allow maps
that are both unsynchronized and reading.
* Also add a test for unsynchronised persistent maps, and update the
GL_Buffer_Updates test to not require a reference image but check each quad
individually for the expected colour.
* This is primarily around initial states - either a resource which is from a
previous frame and maybe wasn't dirtied and needs initial states created for
it when it's modified mid-frame, or a resource that's created and destroyed
all within one frame.
