+\brief Internal function to draw anti-aliased line with alpha blending and endpoint control.
+
+This implementation of the Wu antialiasing code is based on Mike Abrash's
+DDJ article which was reprinted as Chapter 42 of his Graphics Programming
+Black Book, but has been optimized to work with SDL and utilizes 32-bit
+fixed-point arithmetic by A. Schiffler. The endpoint control allows the
+supression to draw the last pixel useful for rendering continous aa-lines
+with alpha<255.
+
+\param dst The surface to draw on.
+\param x1 X coordinate of the first point of the aa-line.
+\param y1 Y coordinate of the first point of the aa-line.
+\param x2 X coordinate of the second point of the aa-line.
+\param y2 Y coordinate of the second point of the aa-line.
+\param r The red value of the aa-line to draw. +\param g The green value of the aa-line to draw. +\param b The blue value of the aa-line to draw. +\param a The alpha value of the aa-line to draw. +\param draw_endpoint Flag indicating if the endpoint should be drawn; draw if non-zero.
+
+\returns Returns 0 on success, -1 on failure.
