fufesou 5278fcab68 fix(cursor): correct native cursor sizing and validate received images (#16213)
* fix(flutter): shrink the unzoomed remote cursor by DPR on macOS and Linux

With "Zoom cursor" off in Adaptive or Custom view, the remote cursor
bitmap was registered at scale 1.0. NSCursor and GdkCursor treat the
bitmap size as logical pixels, so on a HiDPI controller the cursor was
drawn DPR times larger than in Original view (which already passes
1/DPR) and than on Windows (whose cursor path is in physical pixels).
A HiDPI remote such as KDE Wayland sends a 48-64 px bitmap, which then
showed up 3-4x too big on a Retina Mac.

Scale the bitmap by 1/DPR in that case, and scale the Flutter-painted
cursor used while the peer moves the mouse the same way so its size
does not jump. The new branch is an identity at DPR 1 and the Windows
paths are untouched.

* fix(flutter): check the cursor height against the min cursor size

`_checkUpdateScale` computed the scaled height from `width`, so the
min-size clamp never looked at the height.

* fix(flutter): keep the painted cursor hotspot in place when zoom cursor is off

`CursorPaint` subtracted the hotspot in remote pixels and then scaled it
by the canvas scale, but drew the image at scale 1.0, so the hotspot
landed hotx * (1 - scale) logical pixels away from the remote cursor
position. Cursors with a centered hotspot (I-beam, crosshair) were off
by up to half their size in Adaptive view. Subtract the hotspot after
scaling the position instead.

* fix(flutter): read the live DPR and clamp the painted cursor like the native one

CanvasModel caches devicePixelRatio and only refreshes it when the view
style changes, so after the window moves to a monitor with a different
DPR the unzoomed cursor kept the previous monitor's scale. Read it from
MediaQuery instead, which also rebuilds the cursor when it changes.

The native path clamps the scaled bitmap to kMinCursorSize; apply the
same clamp to the painted cursor so a small cursor does not change size
when the peer moves the mouse.

* fix(cursor): match desktop cursor size to peer display density

* refactor(cursor): clarify desktop and web scale branches

* fix(cursor): correct adaptive display scaling and fixed cursor size

* fix(cursor): apply all-display adaptive density on every desktop

* fix: align Wayland software scrolling with input coordinates

* fix: preserve scroll offsets when switching scrolling modes

* fix: correct cursor size and pointer mapping with custom scale

Apply the hovered Linux display density to Custom cursor zoom in All Displays. Refresh scroll fractions after layout so changing the Custom percentage uses current scrollbar extents and detached controllers.

Validated with macOS and Windows component tests, formatting, and static analysis.

* fix(cursor): use `1.0` instead of `1.0/dpr` on Linux -> macOS, Zoom off, Scale adaptive

The mouse cursor currently appears somewhat large.
However, this is difficult to adjust because the cursor size
is fixed while the window size varies; its relative size
depends on the specific desktop environment.

We can modify it if users actually provide feedback.
Ideally, we should check the "Zoom cursor" option.

Further adjustments may also be needed later based on cursor density.

# One branch off upstream v0.13.0, the tag whose crate versions match this stack.
# webrtc-util: reads the Windows adapter list's IPv6 addresses as host-order u16 groups, so every
# one comes out byte-swapped, fails to bind, and ICE gathers no IPv6 host candidate on Windows.
# webrtc-sctp: RFC 4960's 1s RTO floor makes a single loss cost 1-3s on a link whose RTT is 24-64ms,
# and fast retransmit cannot cover a request/response exchange; INITIAL_MTU 1228 also fragments on
# IPv6; and its AIMD pins a lossy long-haul link to MSS/(RTT*sqrt(p)), so a switch sends without
# a congestion window, as KCP does - on by default, `allow-webrtc-congestion-control` opts back in.
# Sending that way, a reordering window keeps a chunk that is merely late from being resent on a
# path that jitters, every DATA chunk asks for its SACK at once so a lost tail is back within an
# RTT at KCP's RTO floors, and bundles of small chunks stay within the MTU. A T3-rtx resends
# everything outstanding when it packs into four packets and otherwise probes with one and lets
# the SACK settle the rest (F-RTO), timed from the latest send, so a stall no longer resends the
# whole backlog behind itself while a short lost tail still comes back at once.
# Pinned by rev, not branch: a fork branch can be rewritten out from under the lockfile.
# webrtc: SettingEngine cannot reach the ICE agent's max_binding_requests, which decides how
# long the answerer keeps checking a pair that has not answered yet.
