Text in port is aligned by center.
In group it is centered in header rect.
When icon is supported, text is aligned vertically with it,
and centered between icon and right group edge.

There problem with intersection, causing absent outline from one side, if not using that magical value 0.001 (any non-zero)

Clipping is enabled automatically, when clip shape is set.

Polygon was not enclosed automatically, when added to path.

What about to deliver to theming, wether ports cover group edge or not?

Might be ever slightly stick out by 1px...

The reason was in zero-width outline pen. No idea, how it happens, but Qt.NoPen looks better.

Original look has all port colors close to dark style, and border color was not contrast, but rather intermediate.
Also use some alpha for text, for some color hinting.
Another trouble with this theme - jack port sel color is painted black, ignoring theme.

When drawen outside, free space between ports is busy.
But when inside, outline is overlaped with text, so themes need bigger height to fix that.

Necessary for classic theme. Now it will look like in latest patchage/ingen series.

Smaller value is guessed by distance between bottom box side and ports.

The drawRect() doesn't have variant, using qreal values, but it accepts QRectF. Even for integer coordinates it uses subpixel positioning, thus always placing them exactly between pixels.
