align Pushbuttons' <pressed>/<unpressed> images

[ronso0]

(I seem to remember a bug report on this but can' find it)

When defining a background image for a pushbutton in <pressed> and <unpressed> tags, it will align left when it's smaller/bigger than the button.
Setting image and alignment per state via qss is working.
Setting alignment via qss and image via button template is not.

Hmmaybe it was this one.
But what I noticed now seems to be different:
Backpath is bigger and nicely scaled to fit the Widget, but it's always aligned to the left, regardless of 'background-position: center;' in qss.
Button text from <state_X_text> is always centered using 'text-align: center;', no matter if <Alignment> in button.xml is defined.
