// This enum describes the kind of the tip shown which combines both the tip
// position and appearance because the two are related (when the tip is
// positioned asymmetrically, a right handed triangle is used but an
// equilateral one when it's in the middle of a side).
//
// Automatic selects the tip appearance best suited for the current platform
// and the position best suited for the window the tooltip is shown for, i.e.
// chosen in such a way that the tooltip is always fully on screen.
//
// Other values describe the position of the tooltip itself, not the window it
// relates to. E.g. wxTipKind_Top places the tip on the top of the tooltip and
// so the tooltip itself is located beneath its associated window.
