I'm not entirely satisfied with this function (or possibly just its
name). What's a bit annoying is that this sometimes it has a side
effect (setting the parameter dirty), which is something one wouldn't
normally expect from a "get". I don't think I have good suggestions
though. It does have a vague resemblance to the
texture_bind_and_dirtify() function in wined3d, so maybe simply call
it param_get_and_flag_data() or something like that?
