### GreSetProcessControl - Remarks

Bounds are returned in graphics model-space coordinates. If a composite transform is applied to the drawing primitives, the bounds values must be transformed back to their original values before merging with the previous bounds values.

Correlation is performed in page-coordinate space on the output of primitives that have been clipped only to the viewing limits and graphics field. Note that correlation is performed for all functions except alphanumeric functions and GreErasePS. Boundary computation is performed for all functions except GreErasePS.
