does anyone have any general advice for Cocoa (/ Quartz 2D) drawing algorithms that don't assume 1 point = 1 pixel?

They don't. 1 point is just the default line width and Mac OS X at this time happens to map one point to one pixel. But Quartz is in no way dependant on that assumption.

but still want the outlines of my drawn objects crispy clean.

If you want to draw lines that are exactly one pixel wide, you would need to know the device's resolution. No idea how to do that.

If you have a seed key I suggest logging into ADC and downloading the Tiger documentation package (look under Resource LIbrary). Then open <file:///Volumes/Tiger_Documentation/referencelibrary/GraphicsImaging/ index.html>, select release notes from the "Display" types popup, and review the last release note, the one related to Quartz.

____ I suggest ALL application developers review this release note and take it to heart. ____

Remember Tiger is under NDA and cannot be discussed on any public mailing list, etc.
