/*****************************************************************************
* IDirect3DVertexBuffer7::Lock
*
* Locks the vertex buffer and returns a pointer to the vertex data
* Locking vertex buffers is similar to locking surfaces, because Windows
* uses surfaces to store vertex data internally (According to the DX sdk)
*
* Params:
* Flags: Locking flags. Relevant here are DDLOCK_READONLY, DDLOCK_WRITEONLY,
* DDLOCK_DISCARDCONTENTS and DDLOCK_NOOVERWRITE.
* Data: Returns a pointer to the vertex data
* Size: Returns the size of the buffer if not NULL
*
* Returns:
* D3D_OK on success
* DDERR_INVALIDPARAMS if Data is NULL
* D3DERR_VERTEXBUFFEROPTIMIZED if called on an optimized buffer(WineD3D)
*
