/**
 * This interface represents a Direct3D resource which is managed by the
 * D3DResourceManager.
 *
 * Subclasses will need to override Release() and the destructor to release
 * the resources held by the object.
 *
 * The subclasses then can be used like this:
 *   class D3DShaderResource : public IManagedResource {
 *               D3DShaderResource(IDirect3DPixelShader9 *pShader) { // ... }
 *      virtual ~D3DShaderResource() { Release(); }
 *      virtual  Release() { SAFE_RELEASE(pShader); }
 *      virtual  IsDefaultPool() { return FALSE; }
 *   private:
 *      IDirect3DPixelShader9 *pShader;
 *   }
 *
 *   pD3DDevice->CreatePixelShader(..., &pShader);
 *   IManagedResource *pShaderRes = new D3DShaderResource(pShader);
 *   pCtx->GetResourceManager()->AddResource(pShaderRes);
 *
 * D3DResourceManager::ReleaseResource() must be used to dispose of the
 * resource:
 *   pCtx->GetResourceManager()->ReleaseResource(pShaderRes);
 *   // pShaderRes is now invalid, it was deleted
 *   shaderRes = NULL;
 *
 * In certain cases the D3DResourceManager may need to release all its
 * resources (like when resetting the device), so the subclasses must be
 * ready to be released at any time, and be able to notify their users.
 * For an example of how this can be achieved see how D3DSDO's
 * pResource field and D3DResource subclass. d3dsdo->pResource is reset when
 * the D3DResource it was pointing to is disposed.
