From e001682b91869ede9cd89b3253dccd137b82d233 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Initial push for RT-35243 - prism should use Monocle's
 platform detection code.  Creates a new prism es2 port (prism-es-monocle)
 which uses the monocle port of glass.  Note that it will not be selected on
 any platform by default; it requires a command line switch
 -Djavafx.platform=monocle -Dembedded=monocle.  Not fully functional yet;
 currently falls back to software rendering partway through initialization
