David Robillard b75b88a1eb Use text to specify combo box padding for better font/display tolerance. 
Consistent mixer strip button height.

The latter works by setting all the button size request heights to the
calculated height of the alphabet.  Thus, all buttons of the same class will be
the same height regardless of their actual text.
