| | | | (...) Hmm. that makes me wonder if the logic of turning of BFC clipping when a part's color is transparent will really work. Because a part may have the main color as 16, and some sections are hard-coded to a transparent color. In this case, the (...) (25 years ago, 10-Dec-99, to lugnet.cad.dev)
