 > > > > Added flag {{{-b}}} and option {{{brdcolor}}} and {{{bgcolor}}} to
 draw background. Also added option{{{font_size}}} as requested. Code was
 separeted from main.c to background.c and draw.c. For background purpose
 in case of {{{-d}}} flag (histogram) added function calc_histogram in
 histrogram2.c

 > Tested, it works. However, the code is not maintainable like this, you
 have too large overlap between `draw` and `background` functions. I
 suggest to merge those functions and use ifs and put some parts into
 separate functions. Also check during compilation for warnings, there were
 a couple of them, probably not serious, but better to fix them.

 That's right, I didn't realize possible problems with maintaining code. So
 I moved it to one function and used parameter {{{draw}}} and if
 conditions. Draw=0 is for calculation and draw=1 for calculation and
 drawing. I don't get any warnings now, so I hope it's OK.
