jdk9 can't run FX2D sketches even with runPropane() fix

[monkstone]

Environment

NB: jdk9.0.4 from oracle includes javafx jars.

Using custom propane (compiled with jdk9.0.4 targeting jdk8) modified to use public runPropane() instead of protected runSketch() test sketch see https://github.com/ruby-processing/propane-examples/blob/master/processing_app/basics/arrays/array_objects.rb.

Expected Behavior

Sketch runs fine with open-jdk8 (with javafx), and also with default renderer (and jdk9.0.4).

Actual Behavior

@headius Tried to compile processing-core with jdk9 found PSurfaceFX.java refers to proprietary code com.sun.glass.ui.Screen which is probably why FX2D sketches wont run with jdk9, something for processing.org guys to fix.

Fixed by creating runPropane method in processing core source. We now compile propane as a single jar (bar opengl).
