Rainbow problem with Turtle Art save image

[walter]

v63 doesn't save images with Rainbow enabled. Permission denied trying to read /home/olpc/isolation/1/uid_to_home_dir/10002/tmp/tmp_45lE6.png while writing to the datastore.

Not sue if this is a datastore problem, a Rainbow problem, or a TA problem... will investigate further.

Did a work-around in v66 (not yet in git) by opening the file in the instance directory explicitly (no longer using tmpfile). Somewhat unsatisfactory because I don't understand the root cause of the problem, but otherwise, it works.
