In `facet_grid`, could the `switch` argument be deprecated, and replaced with a `strip.position` argument?

I find it a bit confusing having the strip.position/switch argument in facet_wrap/facet_grid that does pretty much the same thing.

An idea to make these consistent is to deprecate the switch argument in facet_grid, and add in a strip.position argument for users to use instead.

Where in a grid of 2 facet variables, a character vector of 2 could be provided with "top"/"bottom" always controlling the x, and "left"/"right" would always controlling the y.

Also, It'd be cool if for the grid, it didn't matter which way around you specify the vector - as it would always know top/bottom relates to cols facet variable and right/left to the rows facet variable.
