// Here we only make sure that there's a window and document object in the node
|
|
// environment. We can't do this directly in src/paper.js, due to the nature of
|
|
// how Prepro.js loads the include() files in the various scenarios. E.g. on
|
|
// Node.js,only the files included in such a way see each other's variables in
|
|
// their shared scope.

// Create a window variable valid in the paper.js scope, that points to the
|
|
// native window in browsers and the emulated JSDom one in node.js
|
|
// In workers, and on Node.js when no Canvas is present, `window` is null (but
|
|
// `self` is defined), so we can use the validity of the local window object to
|
|
// detect a worker-like context in the library.
|
|
// Make sure `self` always points to a window object, also on Node.js.

// to the paper.js function scope, and this is the one that is modified here.
