EPR #419347 - Fix a d3d9 memory leak. According to https://msdn.microsoft.com/en-us/library/windows/desktop/bb174386(v=vs.85).aspx: Calling IDirect3DDevice9::GetDirect3D will increase the internal reference count on the IDirect3D9 interface. Failure to call IUnknown::Release when finished using this IDirect3D9 interface results in a memory leak.. Although p3d9devEx->Release() has the same effect as p3d9dev->Release(), for clarification we better use p3d9dev->Release() instead.

* Note: ideally the DXX extension interfaces should be mapped from the DXX perforce branch.
|
|
* This means CAL client spec will need to change to include headers directly from the DXX perforce tree.
|
|
* However, CAL only cares about the DXX OpenCL extension interface class. The spec cannot change
|
|
* without notification. So it is safe to use a local copy of the relevant DXX extension interface classes.
