Description
The memory footprint question was brought up in this morning meeting. So here is a short analysis I have put together to help us better understand what we have achieved and what can be improved on the prism-es2 pipe in term of memory footprint reduction.
Here is the breakdown of prism-es2 related native libraries and jars (note that prism-util.jar is also used by prism-d3d)

Percentage reduction: ~ 32%
Reduced # of native libraries: 2
Reduced # of packages: 1
There is still room where we can further reduce the memory footprint by possibly 50% simply by trimming away unused GL binding methods (in Java and in native). This is a relative safe work which is best to wait till we have a functional X11 port.
