/**
* Prints a warning message followed by a stack trace (to make it easier to figure out what code
* is using the deprecated function).
*
* Most browsers include UI widget to examine the stack at the time of the warning, but this
* includes the stack in the log message for a couple of reasons:
* - This makes it possible to see the stack if the code runs in Node.js.
* - Users are more likely to paste the stack in bug reports they might file.
*
* @param {...*} args - Passed to `console.warn`, with a stack trace appended.
