Problem
 Vertical alignment Bottom of a text box on PowerPoint 2007 seems not to be 
 imported by OOo 3.3.0.
 Text anchor of the text box on OOo 3.3.0 is middle center, not bottom center.

Reproduction
 1. Start PowerPoint 2007.
 2. View - Slide Master.
 3. Choose a text box in a slide layout.
 4. Format Shape - Text Box.
 5. Alter Vertical alignment to Bottom.
 6. View - Normal.
 7. Apply the layout to a current slide.
 8. Fill the text box with some words.
 9. Save the document in .pptx.
10. Open the file with OpenOffie.org 3.3.0.

Expectation
 The text is located at the bottom of the text box.

Reality
 The text is drawn at the middle of the text box.

Notes
 Autofit "Shrink text on overflow" on PowerPoint 2007 is altered with 
 Text "Resize shape to fit text" on OpenOffice.org 3.3.0.
