/* This is the --post-js file for emcc. It gets appended to the

generated fiddle.js. It should contain all app-level code.

|
Maintenance achtung: do not call any wasm-bound functions from
|
|
outside of the onRuntimeInitialized() function. They are not
|
|
permitted to be called until after the module init is complete,
|
|
which does not happen until after this file is processed. Once that
|
|
init is finished, Module.onRuntimeInitialized() will be
|
|
triggered. All app-level init code should go into that callback or
|
|
be triggered via it. Calling wasm-bound functions before that
|
|
callback is run will trigger an assertion in the wasm environment.
