Code review comment for lp:~aacid/unity-2d/unity-2d_pointer_barrier

Some minor code style comments (possibly my code to start with!):

In PointerBarrierWrapper::createBarrier(), please add braces around statements like:

+ if (!m_enabled)
+ return;

Can you add a debug comment explaining that barrier must be horizontal/vertical here:
+ if ((m_p1.x() != m_p2.x()) && (m_p1.y() != m_p2.y()))
+ return;

In PointerBarrierWrapper::decay(), your indentation is wrong, 2 spaces instead of the usual 4.

You should add yourself as an author to pointerbarrier.h
