Currently it is appearently not possible to vertically align text and nodes in TextFlow.

This problem is also outlined here:
http://stackoverflow.com/questions/20759380/how-to-center-an-image-in-javafx


E.g. if you have Texts and Nodes of different heights in the same line, everything is aligned at the bottom/baseline.

It can also be seen here (Sample 4):

Please add support for it.
