For example, when iterating over uniform structure fields, one might want to create temporary strings like "pallete.primary", "palette.outline", and "pallette.shadow". This could be done by overwriting the '.' with a null-byte and calling ralloc_asprintf_append, but that incurs the cost of strlen("pallete") every time...when this is already known. These new functions allow you rewrite the tail of the string, given a starting index. If the starting index is the length of the string, this is equivalent to appending.
