Hi all, Thanks for the comments. My sourceforge ID is dmkaplan. Please add me as a developer. I will commit to the trunk and try to not break things, but I am VERY new to python and it is a possibility. If things don't work out, we can always fall back to creating a branch, though I admit that branching and merging in subversion is a pain. And please do notify me about stylistic issues, etc.
My contributions are likely to be a bit sporadic and selfish in the sense that I am just adding functionality that I use all the time in matlab. But if everyone did that, it wouldn't be half bad.... I don't think the blocking code will be that hard to maintain. It basically just depends on events, callback functions and time.sleep. If those are cross-platform, then it shouldn't be a problem. But only time will tell. My ability and desire to test on multiple platforms is limited - I use ubuntu/gnome-gtk/linux 100%. I plan on spending today sprucing up the patch I sent. Unless anyone is against, I will probably commit and notify in stages so that each piece of the puzzle can be considered separately. I have noticed that the current contour labeling code has its idiosyncrasies, including dealing poorly with label resizing and not being very friendly about unbreaking contours (i.e., it is currently not possible to have a true remove method for ContourSet). I don't plan on fixing these (at least until I have a burning desire to resize labels), but think a contribution that allowed people to resize labels and break-unbreak contours would be useful. I plan on compartmentalizing a bit more ContourLabeler so that each bit of functionality is a separate method - this should make integrating a new LabeledLine class a bit easier as we would just need to attach the right method of one to the other.
