Depends on what you're really trying to do -- would a "small"
or "mini" size Aqua button work (if it were available in Tile?)

In general, if you force a widget to be smaller than it wants to be,
it's not going to look right.

In this case: the button element internal padding is derived by calling
GetThemeButtonContentBounds(), so that (hopefully!) the button text
doesn't extend outside the alloted area.

You could try specifying a large negative padding, to allow the
button text to extend outside the margins.

This is probably coming from the focus ring.

Aqua "full-size" buttons are 20 pixels high, and the ttk::button
also includes space for the focus ring (by experimentation, an
extra two pixels on all sides).
