This one is a really nice idea :)

(** [width font str] returns width of string [str] written in font [font] *)
val width : t -> string -> int;;

Now centering of text: You would like the text centered relatively to what?

The widgets that are being written (You can see something of them in action=
 in=20
Scorch, just press ESC and F2) do have a widget that centers anything insid=
e=20
it, so if you put a text inside such widget it is centered relatively to th=
e=20
whole big widget... So you will be able to center relatively to a menu item=
,=20
or a split-screen half.=20

So they are not completely designed, that's why they are not in main MLG...

Do I understand correct, that you want to center relatively to the context =
on=20
which you draw the string? It is also an interesting idea...

Helpers.delay is a variable (not constant).
The meaning of this variable is, that at least this much time has to pass,=
=20
between two subsequent calls to new_frame_fun.
It is in seconds.
=46or example the value 0.02 means, that we won't allow more than 50 fps.

(I will add this comment to helpers.mli in CVS in moment)
