evas: improve textblock rendering by walking even less in all case. 

We now build a list of item to walk on for each step to just avoid all necessary walking.
It is a slightly more elegant idea than my previous patch even if it only give a speed
improvement of 5% in the best case. Now that render code and the callee only take 1.6%
of the time I am looking at in the benchmark, meaning nothing else to improve here.

This fix the bug spotted in Enlightenment dialog box.
