zero line width

[handrawn]

hands up all those who have ever set line width to '0' instead of 'none'

they are not the same [see line > width in xtreme help], as you might already know

when I imported some AI vector shapes from Expression 3 into xtreme, I was bemused to find that they would not reduce or zoom out properly, despite having scale line width enabled

after a bit of head scratching I noticed the '0pix' setting - changed it to 'none' - problem solved

quick look in the help - '0pix' is a special case: "This draws a line one device-pixel wide" according to the help files

so no matter what you do it is always a [non anti aliased] 1 pix line wide on the monitor

I think I knew this once a long time ago, but I think that a lot these days
