Please review the following interim fix for RT-35243 [Monocle] Prism
should use Monocle's platform detection code.
In a nutshell, this adds a new (monocle) port to prism-es2. It is not
selected by default. There are some trivial changes to ES2Pipeline and
GLFactory to enable command-line selection of the new port. It isn't
functional yet but should be soon. When completed, most of the
prism-es2 functionality should be moved out of native files into java.
