I am building my own display of the driving instructions.
I do not change or modify the instructions, however I try to give some
pictograms to help illustrate the instruction.

This is where things get difficult.
Up to now, I have been looking for keyword combinations to be able to
choose the correct image.
However, the keywords change !

Would it be feasible to return, not only the driving directions text,
but also a fixed "encoded" version permitting custom rendering ?  This
could be as simple as having an integer value representing the
principle action the step involves - turn right, turn left, 3rd exit
of the roundabout, etc ...

What do you think ?
