Messed up the sequence between chatting with Manuel and writing it down

------------------------------------------------------------------------------
  === Notes ===
  
  I can see two possibilities for the implementation:
+  1. Keep track of the font for each character in the TextLM.
-  1. Creating multiple TextLM instances from one FOText instance, splitting the text up by character groups. That would allow to avoid adding additional complexity to TextLM.
+  2. Creating multiple TextLM instances from one FOText instance, splitting the text up by character groups. That would allow to avoid adding additional complexity to TextLM.
-  2. Keep track of the font for each character in the TextLM.
  
  Chatting with Manuel over Skype, he told me to pay attention on the dependencies between LM instances over the !AlignmentContext. Looking at this class shows that it takes values from a single font. So, the difficulty is not really keeping track of which font is used for each character. More difficult is to keep vertical alignment (baselines, ascenders etc.) under control. The situation with the dependencies needs to be improved which could make the implementation of the font-selection-strategy easier. Manuel suggests to follow the first approach above, unless those dependencies can be fixed in which case the second approach would work nicely.
