z1_log - Logging from running on Mac OS

I guess there are couple issue going on here. It looks like from the logs that font's in question aren't be loaded by the font engine, so I'll have to take a closer look at that.

Once the failure occurs the code switches over to font substitutions so one again I'll have to see what font is being used on OSX vs. windows.

It turns out that there was a bug in our content parser logic and cmap logic. When text extraction takes place the toUnicode cmaps are used to map a CID to a String. In our old code we would make a CID to a char but there cases where CID can be represented by more then character.

In the Pro version the issue only showed up with text extraction as it uses the toUnocide cmaps. A little work had to be done to fix the cmap parsing issue. The problem didn't show up at render time because Pro can property read and render CID fonts.

In the OS version the issue showed up at render time and during text extraction. Some work had to be done to first correct the cmap parsing error so we could get the correct String for a given CID and the OFont class was updated to layout and draw the extra characters found in the returned Cmap string.

Accidentally closed this bug instead of 239, this is still an outstanding issue.

Removed an overly assertive throw exception on state that shouldn't affect the code flow. Did a spot check on the document in question and it seems to be rendering the glyphs correctly now.
