I just posted FEZ Raptor using GHI SDK 4.3 with USB and SD storage on Codeshare. Feel free to discuss and make suggestions here.
I have a similar set up. Tried some code to put up items on the display, a text string and a polygon. The polygon uses Stroke and Fill. The Stroke correctly outlines the polygon on the child panel taking its coordinate system from the panel, but the Fill displays offset, apparently because it picks up its coordinate system from the main window canvas rather than from the panel. Could be my code or it could be a bug.
