SCREEN_RAW_PARAMS and dynamic changes

So I'm looking into a fairly complicated CRTC chip (The Signetics SCN2674), and it looks like it can configure the sizes of the offscreen areas and visible areas pretty much at will - with at least one game exploiting that for raster timing.
I know it's the case that there's a call that lets visible area be changed within the driver, because PSX.c uses it, but what about the raw parameters - all I see in screen.c is the static versions for init time?
