/**
 * Creates a 'ghost' bitmap version of the given source drawable (ideally a BitmapDrawable).
 * In the ghost bitmap, the RGB values take on the values from the 'color' argument, while
 * the alpha values are derived from the source's grayscaled RGB values. The effect is that
 * you can see through darker parts of the source bitmap, while lighter parts show up as
 * the given color. The 'invert' argument inverts the computation of alpha values, and looks
 * best when the given color is a dark.
