A domain program that picks one of its patch's control points from data
(Onimusha: Way of the Sword, PPSA27836, selects a corner with v_cmp and
v_cndmask before a buffer_load from the off-chip ring) was refused with
"the tessellation ring or LDS address is not affine in the control point
and relative patch". Computed indices were accepted only for hull LDS
reads.
- The address evaluator gives off-chip EvaluationInput reads the same
dynamic term as hull LDS reads, and a value read from the patch's own
ring or LDS no longer counts as depending on the relative patch index,
since the lowered read takes the patch implicitly.
- When the program also uses its relative patch index as data, the
index is replaced by the grouped patch instead of 0, which left a
computed read's address pointing into another patch. Such reads now
subtract their relative patch term, for hull and domain reads alike;
reads in programs that do not use the index as data keep their address.
- The computed offset must be a whole number of control points, and the
backend clamps the domain gl_in index to the last output control point
as it already does for hull reads.

Without VK_EXT_shader_stencil_export (NVIDIA), stencil reference exports
are emulated by replaying the draw once per value. An export the prover
could not bound to at most 16 values was refused. The replay shader
compares the export's low eight bits, so an unbounded export now
replays all 256 values, and proven values are reduced to their low
eight bits as the comparison sees them.

Windows.Gaming.Input stays on by default, so racing wheels, arcade and
flight sticks, HID pads without an HIDAPI driver and Xbox One/Series
trigger rumble keep working. Hosts where it faults at
Windows.Gaming.Input.dll+0x10a84 set APS5_NO_WGI to turn it off.

On a Windows 10 host with virtual gamepad buses, SDL's WGI backend
faults at Windows.Gaming.Input.dll+0x10a84 a few seconds into every
run (EVO Player PPSA99039: 26 of 26 runs). XInput and HIDAPI still
cover Xbox and DualSense controllers. Set at default priority, like
DIRECTINPUT, so SDL_JOYSTICK_WGI=1 turns it back on.
