How to use the library abclib
-----------------------------


Include the abclib header:

    #include "abclib.h"


To create the clock, call this function:

    void ABC_Make (int hour, int min, int sec, int width, int height, int border)

    	ABC_Make will clear the area before making the clock
    
    	If (border < 0) then a default border margin will be used
    	    appropriate for the size of the clock, otherwise, a fixed
    	    border margin will be used
    
    	If (border < 0) then width and height should not be smaller
	    than ABC_MINSIZE
    
    	If (border >= 0) then width and height should not be smaller
	    than ABC_MINSIZE + 2 * border


Your code should define the following two functions:

    void ABC_SetColor (int color)

    	ABC_SetColor should set the colour to be used in subsequent
    	    calls to ABC_Rect
    	The color argument is one of:
	    0 - background colour
	    1 - inside colour of square
	    2 - square border colour
	    3 - hour colour
	    4 - minute colour
	As defaults, you should use standard background colour for
    	    (color < 2), and standard foreground colour otherwise


    void ABC_Rect (int x1, int y1, int x2, int y2)

    	ABC_Rect should fill the rectangle from lower left (x1, y1) to
    	    upper right (x2, y2) inclusive, in the colour set by
    	    ABC_SetColor.
    	If (x1 > x2 || y1 > y2) the function should do nothing.
