Probably hundreds. And some parameters even have long and short names (e.g. linewidth and lw)! That's not lazy and it's certainly not unusable - on the contrary, it's one of the most usable and useful libraries I've ever used.

Yes! Every time when people talk about
this topic, the argument claiming "named
arguments can lead to bad design because
APIs with many parameters are bad design"
will be raised. TBO, they sound like
"commands with lots of command-line
options are a bad design."

PS: on alternative names such as `linewidth`
and `lw`, designated initializer has a way to
express it:

  struct __generated {
    ...
    union {
      double linewidth, lw;
    };
  };
