chartjs / Chart.js

From what I can tell from testing locally, Chrome doesn't reliably trigger resize events for the final print layout, so using `.resize()` with no parameters doesn't generally work.

I'm not sure if there are circumstances in which the original docs' suggestion of using `.resize()` with no parameters can work; if the original text should be deleted, I can do so.

I also noticed that the TypeScript type definitions for `.resize()` mark the parameters as required, even though the implementation and docs don't require them.
