Sequencer: changes to text effect strip

- default alignment to lower center.
- placement is now relative,
  so changing output size keeps correct placement.
- instead of center override, add align option (left/right/center).

Also don't use pixel-size for setting the font size, on new strips.
Better not have UI prefs impact low level API's.
