@prrace I will need your assistance in confirming that my understanding about the AWT vs 2D split is correct. In particular, `libosxui` gave me some headache, but after trying to dig into the code my understanding ended up being that this is part of Swing which is considered part of AWT, not 2D.

I also looked at `libosx` and `libosxapp` which are located in the general `Lib.gmk` file. I could not easily see that they should have been placed in either 2d or Awt, so my assumption is that they are correctly placed outside these two new files.
