Length of the tip at the bracket start (at istart).
Length of the tip at the bracket end (at iend).
Text to add.
Font size.
Type of the bracket line. Accept codes or names (0 = "blank", 1 = "solid", 2 = "dashed", 3 = "dotted", 4 = "dotdash", 5 = "longdash", 6 = "twodash"), a hex string (up to 8 digits for dash-gap lengths), or a pattern offset to listOf(dash, gap, ...) / listOf(dash, gap, ...).
