Method RuneRelPos

paint/span.go:117–122

RuneRelPos returns the relative (starting) position of the given rune index (adds Span RelPos and rune RelPos) -- this is typically the baseline position where rendering will start, not the upper left corner. if index > length, then uses LastPos

(idx int)

// position where rendering will start, not the upper left corner. if index >
// length, then uses LastPos
func (sr *Span) RuneRelPos(idx int) math32.Vector2 {
	if idx >= len(sr.Render) {
		return sr.LastPos
	}
	return sr.RelPos.Add(sr.Render[idx].RelPos)
}

// RuneEndPos returns the relative ending position of the given rune index
// (adds Span RelPos and rune RelPos + rune Size.X for LR writing). If index >
