@ConnorGBrewster I opened #10226, let's discuss there :) |

I'd like to work on |

I'd like to work on all of the remaining uniform methods, if that's okay |

I'm looking at the stencil* functions. |

Impl copyTexImage2D and copyTexSubImage2D Thank you for contributing to Servo! Please add an `X` inside each `[ ]` when the step is complete, and replace `__` with appropriate data: - [X] `./mach build` does not report any errors - [X] `./mach test-tidy` does not report any errors - [ ] These changes fix #__ (github issue number if applicable). Either: - [ ] There are tests for these changes OR - [ ] These changes do not require tests because _____ Pull requests that do not address these steps are welcome, but they will require additional verification as part of the review process. Implement copyTexImage2D and copyTexSubImage2D for WebGLRenderingContext. Feedback would be appreciated. I did my best to follow the [spec](https://www.khronos.org/registry/webgl/specs/latest/1.0/#5.14.8). Please let me know if I missed anything. As always any feedback, comments,or critiques are very welcome😄 Part of #10209 <!-- Reviewable:start --> --- This change is [<img src="https://reviewable.io/review_button.svg" height="35" align="absmiddle" alt="Reviewable"/>](https://reviewable.io/reviews/servo/servo/11147) <!-- Reviewable:end -->

This is intended to be a meta-bug.
Some of the remaining methods are blocked on #5014 (those that receiveArrayBufferVieworBufferDataSourceand have overrides), but some others can be implemented without problems.I'll try to file individual issues for each remaining deficiency, since some of them can be
E-Easy.General information for WebGL bugs
Click to expand
Spec
The WebGL 1.0 spec is here.
GLES 2.0 spec
WebGL is based on the GLES 2.0 spec, so the WebGL spec often leverages details to it. You can find a PDF version here.
Current Code
DOM
The DOM side of the WebGL code can be found in the following files:
components/script/dom/webglrenderingcontext.rscomponents/script/dom/webglactiveinfo.rscomponents/script/dom/webglbuffer.rscomponents/script/dom/webglcontextevent.rscomponents/script/dom/webglframebuffer.rscomponents/script/dom/webglobject.rscomponents/script/dom/webglprogram.rscomponents/script/dom/webglrenderbuffer.rscomponents/script/dom/webglrenderingcontext.rscomponents/script/dom/webglshader.rscomponents/script/dom/webglshaderprecisionformat.rscomponents/script/dom/webgltexture.rscomponents/script/dom/webgluniformlocation.rsWebGL thread
The WebGL thread is the thread that receives the WebGL messages from the DOM, and either executes it or dispatchs it to the WebRender backend.
You probably don't need to touch anything here, but in case you want to take a look, the file is:
components/canvas/webgl_paint_thread.rsWebGL command definition, execution, and other types
The rest of the WebGL definitions and the command implementations are in
webrender_traits'swebgl.rsfile, in order to be shared by both Servo and WebRender.You'll want to take a look to the
WebGLCommanddefinition and to theapplyfunction.To work actively with it the best is to use a Cargo override.
Note that
WebGLCommandis re-exported fromcanvas_traitsasCanvasWebGLMessagefor legacy reasons (to avoid extra rebase pain while webrender hadn't merged yet).Missing safety checks
