Fixing an FDM support generator bug, where some of the support columns were missing abruptly when going down. The issue was caused by extracting support areas from a grid and filtering the extracted islands by intersection with the input islands. Sometimes the input islands were a bit bigger than the extracted contour, thus some of the samples of the input islands did not fall into the extracted contour.
