Performance rendering in canvas for certain pdf files

[GunterJameda]

Before you start - checklist

• [X] I followed instructions in documentation written for my React-PDF version
• [X] I have checked if this bug is not already reported
• [X] I have checked if an issue is not listed in Known issues
• [X] If I have a problem with PDF rendering, I checked if my PDF renders properly in PDF.js demo

Description

I'm not exactly sure this qualifies as a bug or not, but this is something I faced when parsing a pdf page to png, which uses the exact same method as to render the page in a canvas and after we export it to base64.

The warning message I'm getting is this:

Canvas2D: Multiple readback operations using getImageData are faster with the willReadFrequently attribute set to true. See: https://html.spec.whatwg.org/multipage/canvas.html#concept-canvas-will-read-frequently.

I fixed it by adding a prop in the canvas render context that indicated that it will be read often and the problem went away.

const context = canvas.getContext("2d", {
  willReadFrequently: true,
});

Is it possible to find a way to pass this as a prop or something similar?

I can provide a file as a way to get the test done, but I can't assure the message will popup, since it's an on and off situation.

Steps to reproduce

We need a file that would throw this error and then we should render it and check console.

Expected behavior

Not having the warning message

This file is a good way of seeing what's going on. Check console after opening it.

I see this error all the time, for what it's worth.
