I suspect this may be related to the fact that these fields are initialized to (presumably minimum) values by InitBuiltInResources. We should try overriding them with the known limits here.

jdm · 2018-06-08T14:49:50Z

There is prior art in Firefox.

Use real values for GL maximums when compiling shaders. This matches [the equivalent Gecko code](https://searchfox.org/mozilla-central/rev/c621276fbdd9591f52009042d959b9e19b66d49f/dom/canvas/WebGLShaderValidator.cpp#150-156) and makes a lot of three.js examples render as expected. --- - [x] `./mach build -d` does not report any errors - [x] `./mach test-tidy` does not report any errors - [x] These changes fix #20928. - [ ] There are tests for these changes OR - [ ] These changes do not require tests because _____
