Normally (ideally), tiles (.bmp files) are removed as soon as the JS has displayed them. But occasionally something goes wrong and they are left behind. (For instance, it seems to happen if the user closes the document immediately when it shows up.) Do not leave them on disk until the app starts the next time.
