11 + //Remember x1,x2,y1,y2 are guint unsigned integers
12 + //substract a greater number from a lower is undefined
13 + //this guard that.

Good explanation. However please use correct English grammar.

// Remember that x1, x2, y1 and y2 are guint unsigned integers.
// Subtracting a greater number from a lower one is undefined.
// This guards against that.

14 + if ( x1 > x2)

18 + if ( y1 > y2)

Please use no space after the opening brace ie. "if (y1 > y2)".

30 + if (fabsf (angle - dir_angle) < DEVIANCE || fabsf (angle - dir_angle + 2 *(float)(M_PI)) < DEVIANCE)

Please leave a space after the asterisk ie. "+ 2 * (float)(M_PI)".

Sorry to be nit picking. With these stylistic changes it'll be good to go!
