Module Name:
progbar.h
Abstract:
Declares the functions, variables and macros for the progress bar
utilities. The progress bar utilities manage a single progress bar by
dividing it into slices. Each slice has an initial static size. The
count for each slice is scaled independently, so code can dynamically
change the slice count as an aid to help tick the progress bar more
smoothly.
