AMD hardware compares a sample_c reference against a color texture's red
channel; Vulkan defines comparison sampling only for depth formats, so the
driver refused any compare-sampled texture that is not R32 float or R16
unorm. PPSA21567 compares the same LESSEQUAL, clamp-to-border (opaque
white) sampler against a shadow map and against a 1x1 RGBA8 texture.
For a compare-sampled image whose format is not natively comparable, the
specialization records the paired sampler's compare function, filter,
addressing and border, and the view's reference clamp kind; the image then
binds as an ordinary color texture. The backend fetches the red channel,
applies wrap, clamp-to-edge or clamp-to-border addressing with the
sampler's texel-centre convention (border taps take the border's red),
compares, and blends four comparisons for bilinear filtering. Real depth
formats keep the native path.
Only sample_c / sample_c_lz on 2D and 2D array views, float/unorm/snorm
formats, wrap, clamp-to-edge or clamp-to-border, point or bilinear at one
level are implemented; half-border, the border color table and everything
else on this path throw. The reference clamp for unorm/snorm color formats
is not documented by AMD and is recorded in the technical debt.

IntrusivePtr<T> is three pointers: object, deleter, LibContext. The default
constructors zero them, the copy constructors copy them and take a reference
on the object, operator-> and operator* return the object, and the destructors
drop a reference and hand the object to the deleter when it was the last one.
The last-reference release of a pointer without a deleter needs the object's
destructor and the LibContext memory pool and still throws.

The constructor was a silent stub that left the guest object
uninitialised and c_str threw. The constructor now writes the 0x20-byte
object, c_str returns the buffer or an empty string, and the destructor
throws for a non-null buffer, whose release needs the LibContext
allocator.

Report the process time at which sceAudioOutOutput or sceAudioOutOutputs
accepted the port's last block. A port that never output reports 0, and
waiting with a null pointer does not move the time.

The DCB variant threw "not implemented" while the ACB one wrote a
5-dword packet. Both now go through Agc::Command::WritePrimeUtcl2 and
the size query returns 20 bytes.

Format through the shared wide formatter, truncate to the buffer and
return the full length, as C11 K.3.9.1.3 specifies. A null buffer or
format, a zero or oversized n, %n and a null %s argument are
runtime-constraint violations that return a negative value.

Preserve each bundled module directory under app0 and resolve Linux dependencies across directories. Add integration coverage for both output formats and Windows startup. Refs #556; duplicate-export rejection remains unchanged.
v_ceil/floor/trunc/rndne/fract/sqrt/rsq/rcp/rcp_iflag/log/exp/sin/cos
(f32 and f16) and v_frexp_mant_f32 left NaN, invalid, zero and infinite
results to the driver: signalling NaNs came back unquieted, lavapipe lost
the NaN sign and payload, invalid results were +NaN instead of -NaN, f32
sin/cos at whole and half cycles returned tiny values instead of +0, and
v_fract_f16 of a tiny negative rounded up to 1.0.
Adds an execution test for the 27 opcodes with expected values from
hardware; approximate ops are compared with tolerances from the Vulkan
precision table.

A filter_type naming a subset of the PNG filters used only the first
filter of the mask, because stb's writer is either fully adaptive or
forced to one filter. Decoder::Png::Encode now takes the set of allowed
filter types, filters the rows and writes the chunks itself, and keeps
stb for deflate only. Output for the all-filters and single-filter
cases is unchanged.

SHA1RNDS4/NEXTE/MSG1/MSG2 with a memory source made `--to-intel` fail
the whole relink. The stub now spills a scratch xmm, loads the operand
into it with the unaligned load already used for SHA-256 and runs the
register-form lowering. The SHA1RNDS4 immediate is read after the SIB
byte and displacement. RIP-relative operands still fail: the stub runs
at a different address.

Return the kerning between two character codes at the render scale of
the font, the one set by sceFontSetupRenderScalePixel and
sceFontSetupRenderScalePoint, and fail with NOT_BOUND_RENDERER when no
renderer is bound. sceFontGetKerning keeps its behaviour and shares the
FreeType lookup.

The WriteAddressFromCounter_04_00 measure checks only the address and the
counter pair measure only the address and an even start, as in ampr_emu.
TechnicalDebt records that AMPR commands are larger than the console
records, which affects titles that pad with Nop to an exact offset, and
that the at-start flag of the 04_00 writes is ignored.

s_setreg_b32 has no effect, so a read of the MODE round fields after it
wrote another mode still reports round to nearest even, the rounding the
recompiled code uses. The refused HW_ID test row is named as hardware
register 4, which has no name on gfx10.

sceAgcSetPacketPredication sets or clears the predicate bit of a type-3
packet header, and sceAgcSetRangePredication does so for every type-3
packet between two addresses, skipping type-2 fillers. The z-pass, bool
and disable predication size queries return the size of the
SET_PREDICATION packet sceAgcDcbSetPredication writes.

As in ampr_emu, a counter pair starts at an even counter, and the write
commands take a non-null, 8-byte aligned address; others return EINVAL.
