Saving All Device States with a StateBlock (Direct3D 9)

A state block can be used to capture all device states (see State Blocks Save and Restore State (Direct3D 9)). The following state elements are included in the device state:

Vertex state (see Saving Vertex States With a StateBlock (Direct3D 9)).
Pixel state (see Saving Pixel State With a StateBlock (Direct3D 9)).
Each texture assigned to a sampler.
Each vertex texture.
Each displacement map texture.
The current texture palette.
For each vertex stream: a pointer to the vertex buffer, each argument from IDirect3DDevice9::SetStreamSource, and the divider (if any) from IDirect3DDevice9::SetStreamSourceFreq.
A pointer to the index buffer.
The viewport.
The scissors rectangle.
The world, view, and projection matrices.
The texture transforms.
The clipping planes (if any).
The current material.

To capture all device states with a state block, specify D3DSBT_ALL when calling IDirect3DDevice9::CreateStateBlock.
