D3DDP2OP_DELETEPIXELSHADER	This token is sent to the driver to notify the driver of the deletion of a pixel shader and to give the driver an opportunity to clean up any driver side resources associated with the given pixel shader. Note that this uses the same structure (D3DHAL_DP2PIXELSHADER) as D3DDP2OP_SETVPIXELSHADER.
D3DDP2OP_DELETEVERTEXSHADER	This token is sent to the driver to notify the driver of the deletion of a vertex shader and to give the driver an opportunity to clean up any driver side resources associated with the given vertex shader.

D3DDP2OP_SETPRIORITY	Sets the priority of a managed texture. See D3DHAL_DP2SETPRIORITY.

It is specified by one or more D3DHAL_DP2TEXBLT structures. Because Direct3D drivers maintain all the state necessary to do a blit (for example, texture handles and blending modes), a blit can be accomplished with just the information in the D3DDP2OP_TEXBLT opcode. This new token signals the driver that a texture has to be transferred from system memory into local or nonlocal video memory.
