View::SetDisabledReason, and SettingItem::DisabledReason for settings
pages. When set, it's shown instead of the message worked out from the
enabled pointer, and it also works for items with enabled callbacks.

Tapping a disabled item, or pressing accept on a focused one, shows an
info message naming the setting that has to be on or off, when the item
is disabled by one (SetEnabledPtr/SetDisabledPtr on a config setting).
Items disabled through a callback show nothing.

They still ignore keys and touches. A focused disabled item keeps its
disabled background and gets a thin outline in the focus color instead.

ClickableItem gets a hint text, drawn small under the item's own content,
so it highlights and clicks along with it instead of being a separate
SettingHint view below. Settings pages attach it with .Hint() on the item
it belongs to, and search matches it as part of that item.
SettingHint stays for the few hints that have no item to go in: custom
settings views that aren't ClickableItems, and cheat comments under a title.

The GE clips lit triangles after lighting, interpolating the lit colors. So that lit draws can take the CPU clip
path too, the CPU now lights the ends of the edges it clips, once per vertex, and the vertices clipping makes take
the interpolated colors. They come in a second vertex stream, 8 bytes a vertex (cpulit0 for color0, cpulit1 for
color1, its alpha set where they are to be used), and the vertex shader uses them in place of its own lighting
there (VS_BIT_CPU_LIT). The original vertices keep the shader's lighting.
Every lit draw gets the stream where the CPU lights the triangles it clips (no clip distances, or a game flagged
CorrectCullAfterClip), with a static buffer of zeroes when nothing is clipped, so whether a draw is clipped
doesn't change its pipeline. The colors take attribute locations 3 and 4, those of the skinning weights, which
are never vertex attributes, to stay within GLES2's eight.
Implemented for Vulkan, OpenGL, D3D11 and Metal. Shader cache versions are bumped (new shader ID bit and vertex
format bit).
Regression risk: a new vertex shader input and second vertex buffer on GPUs without clip distances, every lit
draw on those. Tested on Mali (G52, G71, G78) and PowerVR (BXM, GE8320) phones.

Where the GPU can't clip and cull like the GE (no clip or cull distances, the near plane not on the minimum Z,
or a game flagged CorrectCullAfterClip), a draw whose bounding box crosses a Z plane used to go to software
transform. Mixing that with hardware transform on other passes over the same surface made their depth tests
fail on PowerVR.
Now the CPU decodes such a draw to RAM, clips its triangles at the near plane like the GE (into one triangle or
two), drops those entirely beyond the far plane, and range culls the vertices clipping makes. The vertices,
including the new ones interpolated from the decoded ones, then go through hardware transform like the rest.
Lit draws, flat shading and normal-based texgen aren't linear in the decoded vertices, so they're left to the
clip distance where there is one, and culled only when culled whole. Without clip distances, lit draws still
take software transform.
Regression risk: draws that cross a Z plane on GPUs without clip or cull distances, and the flagged games, now
take a new path, on every backend.

Vulkan pipelines can have a second vertex binding, and draws a second vertex buffer for it. OpenGL input
layout entries can come from a second buffer, with its own stride, given with the draw. Metal gets a second
vertex buffer index. Nothing uses them yet.

Only the software renderer keeps the sign it resets, and on the hardware renderers the patch made about 70 of

With clip and cull distances, the GPU drops ground textures on modded maps (#18561): 25551 pixels off the PSP
render on a Pixel 3a, against 1987 with the flag.

With depth clipping, what's behind the near plane is clipped away, but its screen Z still counted, and behind
the eye it's meaningless. Every draw crossing the near plane then took the fragment shader depth clamp on GPUs
without depth clamp, whose depth doesn't match the other draws' rasterized depth, so equal-depth passes failed
(Monster Hunter 3rd HD's ground on PowerVR GLES). The near plane's Z counts instead, and doesn't need the clamp
at exactly zero, where losing what rounds below is the near clip.

The entry hid the Vulkan option on those (Moto G54 and similar) with drivers before 0x005d9576, for the crash
in #18681. Vulkan is the default there, and works on a G54 with that driver. The list is only used on Mac
now, so it and its check are only built there.

Vulkan and Metal pipelines, and OpenGL programs, including those precompiled from the shader cache. Benchmark
times include the compiles, so this shows when two builds differ in how many they need.

The map is only handed out const, and entries only come and go through Insert(), Erase(), Release(), Clear()
and SetBufw(), which keep the index in step. Before, every place that changed cache_ had to update the index
by hand, and one that didn't would leave a dangling pointer for the next block transfer to write through.
A new entry now gets the fields its range needs before it goes in, and the slot of one going to the
secondary cache is erased right away.

Invalidate() runs for every block transfer, and walked the cache_ map from 1 MB before the address,
setting a flag on the few textures that overlap. MX vs. ATV Untamed does about a thousand a second,
each walking about 380 of its 745 textures to find six, and its one 1 MB texture means a tighter bound
on texture size wouldn't help.
Now an array of the textures' address ranges sits next to cache_, sorted by address, with textures
over 64 KB in a short list of their own, so a search only starts 64 KB back. It's updated wherever
an entry enters or leaves cache_ (including the moves to and from secondCache_) or changes its bufw.
It marks the same textures as the map walk did (compared on every call in MX vs. ATV, Wipeout Pure,
God of War: Chains of Olympus and Tekken 6). In MX on a Cortex-A53, Invalidate() went from 889
samples to 27.

Nothing tested sceParseUri, and it showed. Measured on a real PSP by the new
net/parseuri tests:
- A URI without "//" was rejected outright, so mailto:, urn:, about: and even
file:///tmp/x all failed. They parse fine; that is what noSlash is for.
- A fragment ended up appended to the path, because the code looked for "#"
inside the query rather than the whole remainder.
- An empty path came back as "/", because Url insists on one.
- Ports take at most five digits and at most the value 65536, which wraps to
zero; anything longer or larger is refused. A host runs while the characters
are alphanumeric, dot or dash, so an underscore or a bracketed IPv6 address
falls through to the path.
- The three error codes are real and specific - 80433060 bad URI, 804331FE no
output pointer, 80433022 work area too small - where everything returned -1.
Leaving out either area is a size query that succeeds.
So sceUriParse no longer goes through the Url class, which is built for HTTP and
has nowhere to put a fragment.
sceUriEscape kept the wrong two characters: hardware leaves "*" alone and escapes
"~", which is the other way round from RFC 3986. It also fills what it can before
reporting a buffer too small, and leaves the length output alone when it does.
sceUriUnescape was a null entry, so calling it got "library not linked". It is
implemented, including the odd positive return value - one per plain character
and five per escape - that the hardware hands back.
Also lists the two exports libparse_uri.prx has that we did not know about, so a
game calling one is named in the log rather than appearing as a bare NID.

The GE keeps the sign of the z of the last Bezier patch's normal at its last
corner (flipped by patch facing, 0 when sideways or degenerate), and lights a
normal that is exactly zero as that sign times (1,1,1) in model space
(ppsspp-re geprobe exp226-253). Normals the tessellation generates don't take
it. Nayuta no Kiseki and Zettai Zetsumei Toshi 3 rely on it.
Frame dump playback draws a flat +z patch after INIT, as the PSP replayer does
before each replay, so both start from +1.
A run's chunks read the sign and the generated-normals flag, so changing either
waits for the run.

~2us plus ~0.2us per sample on hardware, 15us for 64 (pspautotests

On hardware the vblank interrupt comes as the last line (285) ends, and
hcount wraps to 0 inside it. It takes ~66us of CPU from whatever runs, or
~78us with a handler, which runs ~29us in. It releases the vblank waiters
after the handlers, and they get the CPU once it's done: ~81us after it,
~91us with a handler, ~3us later for each extra waiter. The vblank ends
~818us after it (pspautotests display/vblankphase).
We charged nothing and released waiters from a separate event 48us after
the vblank, and hcount started at 1 because user code rarely sees line 0:
the interrupt takes most of it. Now the interrupt carries those costs, the
waiters are released inside it, hcount runs 0-285 over the real frame
length, and a thread that waits for the vblank pays the ~6us that makes
waiters take turns ~12us apart, as on hardware.

The app's iDepthRasterMode: Auto, Low, Off or Always on. Its default depends on the device (Low on
Android and iOS, Off without SIMD), which a core option can't express, so "Default" picks that.

When the color blend uses the src alpha and the stencil has to be written as alpha, both need the alpha
output, so it took dual source blending, and without it the alpha came out wrong. Where the src alpha is
only in the src factor (SRCALPHA or INVSRCALPHA, with DSTALPHA, INVDSTALPHA or a fixed color for the
dst), the shader now applies the src factor (REPLACE_BLEND_PRE_SRC), which leaves the alpha output for
the stencil on every GPU. That's WipEout Pure's additive glows, among others. On a Mac (MoltenVK), none
of the 1,141 dumps in the frame dump collection change with dual source blending on. With it off,
God of War's black squares and one of WipEout Pure's shield dumps now match its render exactly, and
two more WipEout Pure dumps come closer (3,631 -> 2,793 and 4,642 -> 4,163 pixels off).

On a BXM-8-256 (Moto G54), a vertex shader that writes both clip and cull distances doesn't get culled,
while either one alone works. Geometry the PSP culls got drawn: the ground in DBZ Tenkaichi Tag Team,
scenery in Monster Hunter 3rd. With cull distances off, those draws get clipped and culled on the CPU
instead, and the frame dumps match a desktop GPU's render.

Since a37e1f3660, the CPU waits for the depth rasterizer every time a display list ends, because Syphon
Filter reads its depth buffer for the light flares right after. It reads it in the list's GE interrupt
callback though, and so do Wipeout Pure and Resistance: Retribution. On hardware the drawing is done
when that runs, so that's where to wait now, letting the worker overlap with the CPU until then.
sceGeDrawSync and sceGeListSync wait as before.
With interpreter loads from the depth buffer counted and the worker slowed down by 10-50 ms a batch,
no read in Syphon Filter: Logan's Shadow, Wipeout, Resistance or Midnight Club: L.A. Remix landed while
it was busy. Without any wait, nearly all of Syphon Filter's, Wipeout's and Resistance's did.
L.A. Rush reads its depth buffer only after sceGeDrawSync, and the new compat flag
DepthRasterNoCallbackWait skips the callback wait for it.
10 emulated seconds on a Moto G54 (two Cortex-A78, six A55):
Wipeout Pure 7.24 s -> 6.50 s
Resistance 17.98 s -> 13.26 s
Midnight Club 8.75 s -> 8.01 s
L.A. Rush 5.95 s -> 4.76 s
