"Blur media" hid images and videos in a chat but showed the same media
sharp as the thumbnail of a quoted message and as the last message's
image, video or link preview in the chat list.
Small views are now blurred with the same reveal as chat media. They are
resampled relative to the width they are drawn at, so a thumbnail is
blurred as much on screen as media in a chat, and drawn as the centre
crop the thumbnail shows. In-chat media keeps the same blur.
Blurring the chat list also needs: each last message gets its own blur
state, loaded chat-list videos use it and hide their full-screen play
button while blurred, a right-click on a thumbnail no longer leaves it
revealed on desktop, and leaving a chat mid-scroll no longer undoes
reveals in the list on Android.

* ui: blur media by resampling the preview, not a per-frame effect
Modifier.blur put a BlurEffect on a display-sized graphics layer, so the
Gaussian was re-evaluated on every frame the media was drawn. It also
requires RenderEffect, which Android applies only from API 31, so below
Android 12 media was drawn unblurred while the setting read as on.
A blur and a downscale discard the same thing - detail finer than their
radius - so the preview is now resampled to about one pixel per radius and
stretched back. That runs once when the item composes, needs no
RenderEffect, and removes the detail irreversibly rather than convolving
it. The first resampling step bounds both sides, so no image, however
shaped, can produce a large intermediate.
While the blur hides the media the file is also left unread, so an image
scrolled past is no longer read, decoded at its full size and kept in the
image cache only to be hidden again. blurHidesMedia() is the single
definition that both the drawing and the loading decision use, so they
cannot disagree about whether the media is on screen.
* plans: blur media by resampling the preview
* ui: shorten comments in media blur
* ui: smooth the media blur and match its strength to the old one
Stretching the resampled preview straight to the screen showed its pixel grid. Double it back
up until its longest side is at least half the reference width before drawing, so the last
stretch is short and the tents compose into a bell. The reference width moves from 360 to 400:
fitted against Gaussians, 360 blurred 5-75% more than Modifier.blur did, 400 is within 10% at
every setting.
(cherry picked from commit c0344a9a61)
video().track() in the buffer format callback takes the libvlc input lock,
which stop() holds while it waits for the decoder thread running that
callback. Take the video track from the media info only.
* android, desktop: open group member profile without waiting for the core
Tapping a member avatar awaited apiGroupMemberInfo and apiGetGroupMemberCode
before the profile modal was created. Both are single-row queries, 1-2 ms when
the core is idle, but sendCmd is serialized against everything else the core is
doing, so while it is busy - startup, a batch of incoming events, a long database
operation - the tap produces nothing at all until the core drains.
The modal is now opened first and the two values arrive in state the tap handler
creates, so the profile opens at the speed of the UI. The card is shown from the
member that is already known at the tap, preferring the model's copy once it is
there, so the member no longer has to be written to the model before the modal
can be shown.
* plans: open member profile without waiting for the core
* android, desktop: keep member profile rows in place while they load
The security code and the connection stats arrive after the profile is shown, so
"Verify security code" and the Servers section appeared under the already
visible card and pushed the rows below them down.
They are now rendered from the first frame in their final positions, disabled,
and enabled in place when the data arrives - SectionItemView already drops the
clickable modifier when disabled, so nothing moves. Only what can be decided from
the member known at the tap is reserved: "Fix connection" is not, as it applies
only while a ratchet needs syncing and a placeholder for it would disappear on
nearly every open.
* android, desktop: reserve the network status row with the servers
The reserved Servers section had three rows where the loaded one has four, so
everything below it - "Block member" - moved down by one row when the stats
arrived.
Network status looks like agent state that cannot be predicted before loading,
but connSubStatus returns Just whenever the connection has receiving queues, and
that is the same list that decides whether "Receiving via" is rendered. The two
rows appear together, so the status row is now reserved with them.

fitted against Gaussians, 360 blurred 5-75% more than Modifier.blur did, 400 is within 10% at
every setting.
Skia's raster blur runs at full resolution, so each bar blurred width x (bar + 6 sigma) pixels every frame: about
80 ms per frame for the two bars of a chat at the default radius, which cut scrolling to 5-9 fps on the software
renderer. Scaling the layer cannot help, because a layer's filter is evaluated in device space and the scale is
applied to the sigma too. The bar is now drawn into an offscreen surface up to 8x narrower and blurred there, which
measured 5-6x cheaper and within 0.25/255 of the original.
Blurring a copy means the bar no longer follows the content on its own, so the scroll containers bump a version on
the app bar handler and the bar depends on it.

* desktop: fix rotated video squashed on playback and preview rotated twice
vlc applies the display matrix before a frame reaches the vmem callback, so the
buffer has to be requested with the sides swapped for the transposed orientations,
and the snapshot must not be rotated again by hand. Read the snapshot on the event
thread, where the render callback writes it, and draw the inline playback surface
with FillWidth so a video narrower than the item fills it like its preview does.
Bound the requested buffer: the size comes from a received file, so it is capped by
area, cannot be zero, and a frame that does not fill the bitmap is dropped.
* desktop: harden the video frame path against crafted files
Only transpose the buffer for the track's own sides - the size libvlc passes is
already rotated, so swapping it would recreate the squash for a file declaring a
rotation with a zero-sized track. Copy the frame inside the render callback, on
vlc's thread, where the native buffer is guaranteed to exist, and hand only the
copy to the event thread. Drop a frame rendered with a format the bitmap was not
sized by, or arriving before any buffer was allocated. Divide the pixel budget by
a side pinned at 1 instead of scaling both sides, so a 2000000000x1 declaration
cannot take 45 times the budget. Publish the bitmap only when skia took the
pixels, size the copy after a rewind, and log a failed snapshot conversion
instead of throwing it into callers that have no handler for it.
