* render: turn display-rotated video on the GPU (#3467) A portrait phone clip (4K60 HEVC with a 90° display matrix) dropped ~97 % of its frames: every decoded 4K frame was turned on the CPU, which is too slow at 60 fps, and with the GOP cache's lock held. - GopCache caches decoded frames raw when they need a crop or a rotation; `frame_late` crops and turns them off the lock, and the new `frame_late_unturned` hands them over as decoded with the quarter turns still to apply. - MediaSource gains `video_frame_unturned` (default: the upright frame, 0 turns). MP4 and Matroska implement it; the pool's wrapping sources and the frame server's timed source pass it on. - The render plan folds the turns into the layer matrix of plain layers, and into the GPU effect stage (`LayerFx::turns`): `fs_fx_source` reads the source on its decimated grid through the turn, and the CPU reference decimates then turns, so effects still see the upright picture. Other paths (CPU-only effects, log media, a clean aperture, export) still turn on the CPU as before. * codecs: cache intra-only frames raw too (#3467) Intra-only decoders (ProRes, DNx) cropped and turned every frame before caching it, so frame_late_unturned found it already turned and the GPU had nothing left to do. Their frames are now cached raw like long-GOP output: frame_late still crops and turns them off the lock, and frame_late_unturned hands them over as decoded. * docs: document the unturned-frame entry points (#3467) * codecs: follow main's frame lookup in the unturned paths (#3467) main changed `from_tick` (Matroska) to take the frame rate and `snap`, and MP4 looks frames up with `lookup_time(.., rate, snap)`. `video_frame_unturned` still used the old calls: the Matroska one no longer compiled, and the MP4 one could pick another sample than `video_frame` when `snap` is on. Both now use the same lookup as their `video_frame`. Also repairs the merge of main into this branch: a closing brace was lost in the #3467 test (the test module did not compile) and a blank line was doubled (cargo fmt --check failed). * codecs: test every display turn, crop with turn, drafts and eviction of raw frames * gpu: give the neutral-corrector test LayerFx its turns field Merging main added a LayerFx initializer without the turns field, which breaks compilation of the gpu tests (E0063).
