v3.2.0

• triangle now supports intermediate directions (i.e. 'topLeft'). In most cases, it will now also
  return a smaller object than prior by combining colors into a single 'borderColor' line. (#399)
• triangle no longer relies on borderColorordirectionalProperty`, and therefore has a smaller bundle size.
• fixed a bug withtriangle where passing a unitless number to triangle defaulted to a pixel value. It will instead return the unitless value.
