Hey guys,

Just a heads up: Image resizing appears to be broken on Linux. James: I haven't had time to dig into it, but it's acting like it was earlier on muse and simply hiding/unhiding the window doesn't fix it either.

Log:

Changed RTRTInterface::changeResolution to take a changePipeline
argument and not take a stereo argument.

Added 2 Data 3 argument and 4 Data 0 argument call back functions.

Added ability to resize image.
