Minor issue, but the regex in the export code that detects OPENGL as the
renderer, and thus sets the separateJars variable to true, misses the case
where OPENGL is followed by a space:

size(200, 200, OPENGL );

thus the export packs everything into one jar and the following exception
is thrown:

Error while running applet.
java.lang.RuntimeException
at processing.core.PApplet.createGraphics(PApplet.java:1235)
at processing.core.PApplet.size(PApplet.java:1015)
at processing.core.PApplet.size(PApplet.java:959)

at processing.core.PGraphics.requestDisplay(PGraphics.java:690)
at processing.core.PApplet.run(PApplet.java:1562)
at java.lang.Thread.run(Unknown Source)

Adding a space to the 3rd capturing group in the regex solves the problem,
though there may well be a nicer way: ([^ \\)]*)
-dch

(Tested on v135, WinXp)

Example sketch showing the issue

now fixed for 0136, thanks for the report.
