Generally, it doesn't. It's a matter of accuracy in being able to determine if the destination color is greyscale. This is just a possible bug that popped into my head while thinking about the code, nothing more. (a Mac handles this well, but a PC has a variable number of fraction bits because of the truncation that occurs when an 80-bit float is spilled to a 64-bit stack location) There could be a place where something like the above would send the code around for a loop though. _______________________________________________ Tuxpaint-dev mailing list [EMAIL PROTECTED] http://tux4kids.net/mailman/listinfo/tuxpaint-dev
