This will have to be renamed back or duplicated for MACOSX.

Renamed in one place (noted earlier), but not here. Prefer you didn't rename for
the moment.

                                        params.height,

nit: init on the decl?

it's my C style background I guess. I like to declare things at the top and use
them later. changed.
