Picking points to segment - Qgis+OTB

I have been pushing along the QGIS - OTB Plugin and successfully added map-canvas picking to inject seed points for region growing into the plugin. Though issues remain in reprojecting from map-coordinates to pixel-coordinates for the purposes of forwarding to OTB which works in pixel coordinates due to its ITK heritage. I have had some success with my test cases and the plugin builds on various platforms - Mac, Debian and Windows MSVC, yet issues remain. Such is the nature of distributed development, we will get there through the open process soon enough.
