// To ensure that the standalone PDF.js image decoders have the same
// browser/environment compatibility as the regular PDF.js library,
// the standard set of polyfills are thus included in this build as well.
//
// Given that the (current) image decoders don't use all of the features
// of the complete PDF.js library, e.g. they are completely synchronous,
// some of the larger polyfills are thus unnecessary.
//
// In an attempt to reduce the size of the standalone PDF.js image decoders,
// the following polyfills are currently being excluded:
//  - ReadableStream
//  - Promise
//  - URL
