Add initial support for WebGL compressed textures This patch is an initial implementation of WebGL compressed texture support, it contains - functions for registering and querying compressed texture extensions - initial implementation of `CompressedTexImage2D` and `CompressedTexSubImage2D` and their parameter validation - implementation of S3TC (DXT1, DXT3, DXT5) and ETC1 extensions as examples What's still missing: - some of the parameter validation steps are missing - the pixel comparison tests fail for more complex cases (I'm probably missing something trivial at the GL calls) Related: #10209 and #20594 cc @jdm @zakorgy --- - [x] `./mach build -d` does not report any errors - [x] `./mach test-tidy` does not report any errors - [x] Related issues: #10209, #20594 - [x] There are tests for these changes <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="34" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/23226) <!-- Reviewable:end --> |
