this breaks the spotlight example included with the p5 distribution, along
with several other bits of code on the board that will reproduce the issue:

happens with P3D (and OPENGL)

might be a regression from not creating new variables that was included in
P3D between 108 and 109, but there doesn't seem to be a good reason why
this would be the case.. however perhaps those variables are used later and
in a different way, and they're expected to be their own memory?

haven't tried a diff of other parts of the source that could have broken
between.. assumption is that it would be in PGraphics3. also need to check
if replacing PGraphics3 with the old one will make the issue go away..
simple enough but needs to be done with a copy of the 108 and 109 sources,
because the superclass (PGraphics) changes completely in 110 and the diffs
will be a total mess.

fixed in revision 0112.
