22/**
23 * GtkCssLocation:
24 * @bytes: number of bytes parsed since the beginning
25 * @chars: number of characters parsed since the beginning
26 * @lines: number of full lines that have been parsed. If you want to
27 * display this as a line number, you need to add 1 to this.
28 * @line_bytes: Number of bytes parsed since the last line break
29 * @line_chars: Number of characters parsed since the last line break
30 *
31 * Represents a location in a file or other source of data parsed
32 * by the CSS engine.
33 *
34 * The @bytes and @line_bytes offsets are meant to be used to
35 * programmatically match data. The @lines and @line_chars offsets
36 * can be used for printing the location in a file.
37 *
38 * Note that the @lines parameter starts from 0 and is increased
39 * whenever a CSS line break is encountered. (CSS defines the C character
40 * sequences "\r\n", "\r", "\n" and "\f" as newlines.)
41 * If your document uses different rules for line breaking, you might want
42 * run into problems here.
