There are 4 states. Then, for each state, there is a function to draw the progress bar and another one to draw the background. For example, draw_theme_bar_H() and draw_theme_bkg_H().

Then, they're called like the following.
```
            drawProcs[0]( &pdi, 0, gapStart); /* Draw progress bar */
            drawProcs[1]( &pdi, gapStart, gapEnd); /* Draw background */
            drawProcs[0]( &pdi, gapEnd, barSize); /* Draw progress bar */
```
