* `ImageDecoder` in the worker. Primarily used to improve performance of
* image conversion/rendering.
* The default value is `true` in web environments and `false` in Node.js.
*
* NOTE: Also temporarily disabled in Chromium browsers, until we no longer
* support the affected browser versions, because of various bugs:
*
* - Crashes when using the BMP decoder with huge images, e.g. issue6741.pdf;
* see https://issues.chromium.org/issues/374807001
*
* - Broken images when using the JPEG decoder with images that have custom
* colour profiles, e.g. GitHub discussion 19030;
* see https://issues.chromium.org/issues/378869810
*
* @property {number} [canvasMaxAreaInBytes] - The integer value is used to
* know when an image must be resized (uses `OffscreenCanvas` in the worker).
* If it's -1 then a possibly slow algorithm is used to guess the max value.
