Registers the rendering parameter of the background plane.

Prototype declaration:

> `

>     KMSTATUS KMAPI
>     kmSetBackGroundRenderState(
>             IN  PKMVERTEXCONTEXT    pVertexContext
>     );

> `

Description:

>     This function registers the members (listed below) of the KMVERTEXCONTEXT
>     structure that was set up by kmProcessVertexRenderState in the system as
>     the rendering parameters for the background plane.  For the BG plane settings
>     that are specified by kmSetBackGroundPlane() subsequent to calling this function,
>     these parameters and the value of KMVERTEXCONTEXT set by pVertexContext are valid.

>     Members that are referenced:
>     	pVertexContext->GLOBALPARAMBUFFER
>     	pVertexContext->ISPPARAMBUFFER
>     	pVertexContext->TSPPARAMBUFFER
>     	pVertexContext->TexturePARAMBUFFER

Parameters:

>     pVertexContext(input)
>             This parameter is a pointer to KMVERTEXCONTEXT.

Return values:

> Value | Explanation
> KMSTATUS_SUCCESS | Success
