// My original design for clicking/interactivity/transparency:
// Basically I wanted a really simple way to show which element
// in a group of clickable geom elements is currently
// selected. So I decided that all the non-selected elements
// should have alpha transparency 0.5 less than normal, and the
// selected element should have normal alpha transparency. Also,
// the element currently under the mouse has normal alpha
// transparency, to visually indicate that it can be
// clicked. Looking at my examples, you will see that I
// basically use this in two ways:
// 1. By specifying
// geom_vline(aes(clickSelects=variable),alpha=0.5), which
// implies a normal alpha transparency of 0.5. So all the vlines
// are hidden (normal alpha 0.5 - 0.5 = 0), except the current
// selection and the current element under the mouse pointer are
// drawn a bit faded with alpha=0.5.
// 2. By specifying e.g. geom_point(aes(clickSelects=variable)),
// that implies a normal alpha=1. Thus the current selection and
// the current element under the mouse pointer are fully drawn
// with alpha=1 and the others are shown but a bit faded with
// alpha=0.5 (normal alpha 1 - 0.5 = 0.5).
// Edit 19 March 2014: Now there are two styles to show the
// selection, depending on the geom. For most geoms it is as
// described above. But for geoms like rects with
// aes(fill=numericVariable), using opacity to indicate the
// selection results in a misleading decoding of the fill
// variable. So in this case we set stroke to "black" for the
// current selection.
