Partially addresses #1282.
An extra black pixel is drawn along the left edge of the waterfall because the code that draws the black areas to the left and right of the waterfall uses
drawRect
which draws the outline of a rectangle, which extends down and to the right by one pixel beyond the rectangle's dimensions.I've changed the code to use
drawLine
instead, which draws a single line of pixels.
