NAME
       dtk_create_line - Create and modify line shape

SYNOPSIS
       #include <drawtk.h>

       dtk_hshape dtk_create_line(dtk_hshape shp,
		       float x1, float y1, float x2, float y2,
		       const float *color);

DESCRIPTION
       dtk_create_line() creates a line between the points (x1,y1) and (x2,y2).

       shp and color have the same usage and meaning as for other shape creation function:

	* shp  can be used to modify a previously created shape. If it is non-null, the handle will be used to modify the shape referenced by shp:
	  no new shape is created and the returned value is ensured to be shp in case of success, NULL otherwise. If shp  is  NULL,  the  function
	  will attempt to create a new shape.

	* color should point to a 4 float array containing a normalized RGBA value (i.e. each component is between 0.0 and 1.0).

RETURN VALUE
       In  case  of  success these functions return the handle to the newly created or modified shape. If the shp argument is non-null, the handle
       returned is the same value. In case of error, NULL is returned.
