* Since {@link Canvas} doesn't provide a way to draw a half-rounded rect, this means that we
* need to coalesce the backgrounds for adjacent sections and draw them as a single round rect.
* This method tracks the top of each rect we need to draw, then iterates through the visible
* sections. If a section is not adjacent to the previous section, we draw the previous rect
* behind the sections we've accumulated up to that point, then start a new rect at the top of
* the current section. When we're done iterating we will always have one rect left to draw.
