# This file is loaded within Task's worker process. It will attempt to invoke
|

# any message with a 'method' and 'args' key on the global `handler` object. The

# initial `handler` object contains the `start` method, which is called by the
|
|
# task itself to relay information from the window thread and bootstrap the
|
|
# worker's environment. The `start` method then replaces the handler with an
|
|
# object required from the given `handlerPath`.
