Skia's dithered gradient shaders cost ~10ms per full-screen pass on
Mali-class TV GPUs: the two spotlight scrims alone were ~20ms of a 27ms
raster frame, while flat blended quads at the same coverage are ~free.
Bake axis-aligned LinearGradients once into cached 1x1024 premultiplied
strip textures drawn as stretched quads (shader fallback for unsupported
shapes and the first frame). Converted the spotlight, TV detail backdrop,
app-bar scrims, rail bleed, person-card overlay, and the video-controls
scrim, which now also keeps one widget type across hasFrame flips so the
controls subtree survives in-place source switches.
Scripted-browse on a Mali-G31 box: draw p50 27.5ms -> 7.1ms, swap block
20.3ms -> 0.9ms, janky draws 69% -> 2%; screenshots pixel-identical.
* fix(plex): show PGS subtitles when transcoding
Bitmap subtitles (PGS/VOBSUB) disappeared from the menu while transcoding on Plex, leaving only "Off". The MKV transcode already supports them, so embed them in the stream like text subs. Now they show up and can be turned on.
* fix(plex): give bitmap subtitle codecs the right sidecar extension
getSubtitleExtension fell back to .srt for vobsub, pgssub and dvb subs. Map them to .sub/.sup so it stays consistent with isImageSubtitleCodec and any sidecar URL or download uses the correct extension.
The keyboard is a navigator route, so a screen swapping out its form
left it floating over the new content. showTvVirtualKeyboard now
returns a route handle and the field host closes it on dispose.
The TV keyboard dialog froze the field's callbacks at open time, so the
search screen's done key fell through to unfocus() once results arrived.
Resolve callbacks against the latest field widget at invoke time, and
give the search screen a TV submit handler that focuses the first result
or flushes the pending debounce.
Adds nullable canPop + onSystemBack to OverlaySheetHost. When canPop is
set, the host installs its own PopScope that closes an open sheet on a
system/route back instead of popping the screen; null keeps today's
behavior. Lets screens drop their hand-rolled sheet-back PopScopes.
