T# word1 MIN_LOD (unsigned 4.8, in levels of the whole surface) was
rejected. Sampled views now chain VkImageViewMinLodCreateInfoEXT
(VK_EXT_image_view_min_lod, enabled when the device offers the minLod
feature). Its minLod counts levels of the whole image exactly as MIN_LOD
counts levels of the whole surface, because the image holds every mip and
the view starts at BASE_LEVEL.
- A clamp at or below BASE_LEVEL cannot change which level a sample reads
and is left off; one past the view's last level is bounded by it (the
view selects that level anyway, and Vulkan requires the bound).
- A clamp that binds on a device without the feature throws.
- The texture cache already keys by the eight descriptor words, so views
with different clamps are not shared.
- Storage views address one level: a clamp at or below that level is
accepted, one above it still throws.
Only the lines this branch added lose their comments; the commits before
keep them, with the reasoning behind each change, for whoever digs into
that code later.

Both suites stopped at their first stale expectation, so nothing after
it ran; the BDA device tests did not link.
- the BDA device tests define the one recorder entry Resources.cpp
reaches (no recorder) and fail loudly on the others
- Buffer::Invalidate refuses memory that is not host mapped again (lost
in 8a69fef); the device tests expect it for a device-local buffer
- APS5_PIN_WAIT_MS (60000 by default, unchanged) bounds the wait before
a mutation of a leased range is refused, and the refusal names it; the
graphics tests set 200 ms, as they expect about a dozen refusals
- the expectations follow the behaviour the code chose since: a buffer's
four-DWORD V# is refused as a T#, a sampler exceeds the mock's zero
sampler slots, a V# at unmapped memory binds its committed pages only,
a rect-list fragment input without a vertex export reads as zero,
detiled rows span the padded block width, mip ranges are checked in
address order, block-compressed and 128/129/132 formats use render
target tiling, an XOR swizzle is refused only over a base that is not
64 KiB aligned, DCC and partial mip chain views decode, a cube reads as
a 2D array, the sampler fixture's max LOD fits the 4.8 field, a BDA
program with barriers is accepted, a tessellation control stage is
refused, a corrupt request fails on its signature and a newer one on
its version
- the DCC comment in the texture decoder no longer claims metadata
compression is refused

Replaces the synchronous per-command execution model, and with it the
upstream render-target, pipeline-cache, tile-buffer, batched-draw and
memory-ownership commits (5a280ce, 7ed5a0b, 46c799d, 598caac, 40df528),
whose files are removed.
- Recorder: one open command buffer per device; dispatches, resident
draws, uploads, write-backs, labels, fills and copies record into it;
timeline-semaphore serials let drains wait without the GPU mutex;
completions run in order at reap.
- one worker thread per PM4 queue; labels and stores written by the GPU
into the host import; GPU-side DISPATCH_INDIRECT; the buffer-fill
kernel replaced by vkCmdFillBuffer; a dispatch cache validated by
write watch; filler packets tolerated; rejected submissions dumped.
- guest memory: page-state cache, 64 KiB write generations, host imports
with VK_EXT_external_memory_host, persistent mirrors of the executable
image, GPU copies of misaligned sub-ranges.
- textures: shader-written images stay resident with deferred
write-back (adjacent-generation rule for packed video planes), sampled
views of storage images, DCC key handling, addrlib swizzle equations,
bidirectional detiler.
- draws: MRT, more formats, dynamic viewport/scissor, cached pipelines,
resident 64 KiB targets, draws recorded into the recorder.
- ShaderResources: two-stage build, descriptor and sampler caches, a
content-keyed resource cache; presentation from the resident image.
- a label deferred behind a completion is no longer re-stored by the
CPU at reap time unless a write-back overwrote it.
