tile() with background color

[neave]

libvips dszave provides a background option to set the default background color of the tiles, but this option does not seem to work in sharp. Am I doing this incorrectly or is this option not implemented?

Example:

sharp('file.png')
	.tile({
		size: 512,
		overlap: 0,
		layout: 'google',
		background: '#000'
	})
	.toFile(tilesDirectory, (error, info) => {
		done();
	});

Hi, as you've seen, the background option of libvips' dzsave operation is not currently exposed in sharp.

Happy to accept a PR to add this if you're able.

OK thanks @lovell. I've had a go but C++ isn't my strong suit. See PR #1924.
