setSize
Sets the size for the icon. The units depend on the scaling mode, if it's set to Scaling::WORLD_SIZE, the size is in meters near the equator, the size will not be stretched near the poles. If it's set to Scaling::SCREEN_SIZE or Scaling::CONST_SCREEN_SIZE then the size is in screen density independent pixels (dp or dip) or normal pixels, depending whether setScaleWithDPI was set to true or false respectively. If set to -1, unpadded bitmap width will be used instead. The default is -1.
