/// - vertical (bool): Whether the element is vertical or horizontal.
/// - If false, port 0 is placed on the west side and port 1 on the east.\
/// - If true, they are on the north, respectively the south sides
/// - gap (number, ratio): The gap between both sides
/// - if it is a number (int or float), it is interpreted as an absolute canvas-unit length
/// - if it is a ratio, it is interpreted as proportional to the capacitor's length (width if horizontal, height if vertical)
/// - scales (array): A pair of ratios, the sizes of the sides relative to the capacitor's height (width if vertical).
/// - symbols (array): A pair of content or strings (or none values) to attach on the sides of the capacitor
