| /* |
| * This externs file prevents the Closure JS compiler from minifying away |
| * names of objects created by Emscripten. |
| * Basically, by defining empty objects and functions here, Closure will |
| * know not to rename them. This is needed because of our pre-js files, |
| * that is, the JS we hand-write to bundle into the output. That JS will be |
| * hit by the closure compiler and thus needs to know about what functions |
| * have special names and should not be minified. |
| * |
| * Emscripten does not support automatically generating an externs file, so we |
| * do it by hand. The general process is to write some JS code, and then put any |
| * calls to CanvasKit or related things in here. Running ./compile.sh and then |
| * looking at the minified results or running the Release trybot should |
| * verify nothing was missed. Optionally, looking directly at the minified |
| * pathkit.js can be useful when developing locally. |
| * |
