Ends an active technique.
This method has no parameters.
This method always returns the value S_OK.
All rendering in an effect is done within a matching pair of ID3DXEffect::Begin and ID3DXEffect::End calls. After all passes are rendered, ID3DXEffect::End must be called to end the active technique. The effect system responds by using the state block created when ID3DXEffect::Begin was called, to automatically restore the pipeline state before ID3DXEffect::Begin.
By default, the effect system takes care of saving state prior to a technique, and restoring state after a technique. If you choose to disable this save and restore functionality, see D3DXFX_DONOTSAVESAMPLERSTATE.
