and fixes small problems with pose and soft body impulses.

+ * The anchor hardness percentage(together with general hardness settings
+ * set with ephysics_body_soft_body_hardness_set()) will define how the soft
+ * body is supposed to deform.
+ *
+ * By default EPhysics will calculate the anchor hardness depending on the
+ * general hardness settings, by default it`s set to 70% of general hardness on
+ * soft body and a fixed 80% for cloths.
+ *
+ * Anchor hardness will result on a contrary force to impulse and velocities
+ * applied to soft bodies. So it implies on force reduction.
+ *
+ * @note Since it`s a percentage value @p hardness will range from 0 - 100.
