This is a reland of 6f0b021dbf1ac6f66690eff7ae2cad2ac2c2df89. It also renames CreateDefaultTextureView to CreateDefaultView in a test that landed after the tryjobs for the reverted patch passed. Original change's description: > Rename texture.createTextureView to createView to match WebGPU > > Bug: chromium:877147 > Change-Id: I186fc26054cc6729c859a4161c755a1133dc0bca > Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/6360 > Commit-Queue: Austin Eng <enga@chromium.org> > Reviewed-by: Corentin Wallez <cwallez@chromium.org> Bug: chromium:877147 Change-Id: I8e1a1adc07ad2c78081ae3cb0fa2bdb648b39c50 Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/6361 Reviewed-by: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Corentin Wallez <cwallez@chromium.org> Commit-Queue: Austin Eng <enga@chromium.org>
