The example is invalid. (spaces)

> "-tile_rows  row  -tile_cols  col"

This way, the options are typed, have min, max and default values,
without needing any code to write and maintain.

if you mean "-tile rowsxcols", there's no option type for this, 
unless you would want to mis-use the video size type for it.
Otherwise you'd need to make it string and write all the parsing
and checking code for it. 
Do you think that it would be worth the effort?

Also, in most use cases, you will probably have rows or cols,
rather than both..
