This introduces a new field 'doYuvToRgbConversionOnly' in ExternalTextureParams to have the WGSL only do yuv->rgb conversion for better performance. User studies shows that users don't really care about the Gamma difference between 2.4 and 2.2. https://source.chromium.org/chromium/chromium/src/+/main:ui/gfx/color_space.cc;l=1022;drc=a1dbb594a6741a400db35fe3678e77bad2504ea4 Bug: dawn:1082 Bug: dawn:1466 Change-Id: I61c0fe65c5969d8a61c267c202c8dd64c259ed8a Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/92901 Kokoro: Kokoro <noreply+kokoro@google.com> Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Jie A Chen <jie.a.chen@intel.com>
