The zero-copy VAAPI encoder emitted full-range BT.709 NV12 but wrote no color
tags, so players assumed limited range and stretched it — the H.264 output
looked dark and oversaturated (preview and VP9/software were fine).
- Rgba2Nv12 takes `full_range` and applies the matching Y/chroma scale+offset
(limited 16-235 / full 0-255) via a uniform; the encoder sets color_range +
bt709 colorspace/primaries/transfer tags to match. ffprobe-confirmed.
- New ColorRange { Limited, Full } on VideoExportSettings (default Limited, the
universally-correct choice; serde(default) so saved settings still load),
surfaced as a "Color range" dropdown in advanced export settings for H.264.
The swscale software fallback still emits Limited regardless of the toggle
(Full only affects the VAAPI zero-copy path).
