static

Find the position in a string where an x coordinate falls.

Parameters

fstyle	style for this text
string	UTF-8 string to measure
length	length of string
x	x coordinate to search for
char_offset	updated to offset in string of actual_x, [0..length]
actual_x	updated to x coordinate of character closest to x

Returns: true on success, false on error and error reported

		size_t *	char_offset,
		int *	actual_x
	)

static

Find where to split a string to make it fit a width.

Parameters

fstyle	style for this text
string	UTF-8 string to measure
length	length of string
x	width available
char_offset	updated to offset in string of actual_x, [1..length]
actual_x	updated to x coordinate of character closest to x

Returns: true on success, false on error and error reported

On exit, char_offset indicates first character after split point.

Note: char_offset of 0 should never be returned.

Returns: char_offset giving split point closest to x, where actual_x <= x else char_offset giving split point closest to x, where actual_x > x

Returning char_offset == length means no split possible
