so/pipfun.c & so/pnote.c: Refine display and support widescreen display.

* so/pipfun.c: Add function `[outs/prints]_centered()` for centering display.
* so/pnote.c: `show_pnote()`: Fix passing an extra argument to `prints()`.
* so/pnote.c: `show_pnote()`: Eliminate an unnecessary `sprintf()`.
* so/pnote.c: Refine vertical layout.
* so/pnote.c: Make note texts centered.
* so/pnote.c: Center some UI elements with `[outs/prints]_centered()`.
* so/pnote.c: Change some `prints*()` to safer `outs*()`.
