Helper lambdas to reduce duplicate code. Taking colors as vec3b because Scalar has too many implicit conversions.

Most basic, drawing a bar starting at the right place, right height, of designated width and color.

Draw a bar that's a fraction of the total length, based on the units passed in (computing the fraction internally), in a given color.

Drawing overlapping rectangles to avoid noisy lines at borders. So, the bottom one will always be the full size... This we call the "base bar"

A list of the layers, bottom to top, with their individual portions and their color, to iterate through.

Iterate through the layers.
