| Reference tests (reftests) for WebGPU canvas presentation. |
| |
| These render some contents to a canvas using WebGPU, and WPT compares the rendering result with |
| the "reference" versions (in `ref/`) which render with 2D canvas. |
| |
| This tests things like: |
| - The canvas has the correct orientation. |
| - The canvas renders with the correct transfer function. |
| - The canvas blends and interpolates in the correct color encoding. |
| |
| TODO(#918): Test all possible color spaces (once we have more than 1) |
| TODO(#921): Why is there sometimes a difference of 1 (e.g. 3f vs 40) in canvas_size_different_with_back_buffer_size? |
| And why does chromium's image_diff show diffs on other pixels that don't seem to have diffs? |
| TODO(#1093): Test rgba16float values which are out of gamut of the canvas but under SDR luminance. |
| TODO(#1093): Test rgba16float values which are above SDR luminance. |
| TODO(#1116): Test canvas scaling. |
| TODO: Test transferControlToOffscreen, used from {the same,another} thread |
