			(This is a combination of 31 commits) * Fix Linux compilation. * Fix mac compilation. * CI compile fixes. * printf's size_t is %zu. %tu would be unsigned ptrdiff_t. * No non-ref Maybe args. * MOZ_CRASH for noreturn * Handle implied texture sizes, rewrite comment stripping. * Replace e.g. WebGLProgramInner with simpler webgl::ProgramKeepAlive. * Bounce ValidateProgram call off driver. * Uniform name length limit, cubemap fb-attach, non-array uniforms, undersized texImage views. * alignas for uint8_t[sizeof(float)*N] pun buffers. * CC fixes? * Fill attrib0Active. * Repair max-warnings limit. * This is basically required in order for CI's logging to not explode. * Don't cache WebGLMemoryTracker. * Deleted prog/shader error, no texSubImage(null), client-side fingerprint resist for exts. * Fix GetUniformIndices and MakeRangeFromView. * CC Traverse base class from within derived class to fix leaking the world. :( * PauseTransformFeedback * TexImage video fastpath * GetFragLocation for arrays * Forbid BindBufferRange during TF * Mark tests and fix RBAB query and test. * Change(!) query deletion behavior to match spec. * Mark conformance2/query/query.html failing for now. * Implicitly EndQuery on DeleteQuery while spec is in flux. * Fix error code for test. * RAII LruPosition for WebGL context limit. * Include std::list. * Mark CompileResult and LinkResult.pending as false when retrieved. * Hold strong-ref to NotLostData during Run<> to prevent LoseContext=>UAF. * Don't assume GetUniformLocation(foo+'[0]') means foo is an array. * Don't assume !mCanvasElement means !!mOffscreenCanvas. * Handle composition while context-lost. * All non-value-init members must be const or have inline init. * Mark passing tests on Linux. Depends on D54019 Differential Revision: https://phabricator.services.mozilla.com/D55739 --HG-- extra : moz-landing-system : lando
