/**

|
|
*
|
|
* \brief Smart Parameter Management.
|
|
*
|
|
* With large amounts of geometry the device can run out of Parameter Buffer
|
|
* (PB) as no more free pages are left in the freelist to allow the PB to grow.
|
|
* In such cases the render is split into multiple partial renders (PRs) to fit
|
|
* within the memory constraints. Each PR produces intermediary results until
|
|
* they have all completed, producing the final scene equivalent to what would
|
|
* have been produced by the original render.
|
|
*
|
|
* SPM comprises all the necessary work required of the driver to manage the PB.
