/// A state block is a collection of device state, and is used for saving and restoring device state. Use a state-block mask to enable subsets of state for saving and restoring. The <see cref="SharpDX.Direct3D10.StateBlockMask"/> structure can be filled manually or by using any of the D3D10StateBlockMaskXXX APIs. A state block mask can also be obtained by calling <see cref="SharpDX.Direct3D10.EffectTechnique.ComputeStateBlockMask"/> or <see cref="SharpDX.Direct3D10.EffectPass.ComputeStateBlockMask"/>. Differences between Direct3D 9 and Direct3D 10: In Direct3D 10, a state block object does not contain any valid information about the state of the device until <see cref="SharpDX.Direct3D10.StateBlock.Capture"/> is called. In Direct3D 9, state is saved in a state block object, when it is created. ?
