// Returns the data associated with a Mime type, returning NULL if that data
// doesn't exist. Note: because of the inherit raciness of clipboard access,
// this may return NULL even if you just verified that it exists with
// GetAvailableFormatMimeTypes(). We don't want to provide one API to return
// the entire clipboard state because the combined size of the clipboard can
// be megabytes, especially when image data is involved.
