* 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.
