What do we need to change in the android source code to get the resolution of 1360x768 working in an emulator?

The following changes let me start an emulator 1280x720

A: 

Apparently you needed some extra memory for a large (1280x720) screen, but this is not sufficient for an even larger (1360x768) screen. So, allocate even more memory?
