Testing various fonts and sizes I realized there were still problems
with the layout of the bit labels. Also I reorganized the code so that
lambdas are defined just before they are used. Comments needed
punctuation too.
Part of the problem was that I had been assuming all along that the
check boxes were ImGui's originals which are always square. In actuality
the width is determined by the width of the character for '0'. Also
ImGui table was adding spacing to separate cells which made the boxes
not start at same place as column. Also for some reason using indent of
zero didn't work as expected but using 0.1 pixels worked. With those
problems fixed it is fairly easy to make sure the labels are centered at
the box except when the first mantissa checkbox gets a label which is
wider that the box width. Before and after show results for different
fonts.
