Good idea (although I don't think it's a TeX-specific problem at all).

And not useful for printing... I know how to work around it; I'm just 
disgusted by what's needed to work around it (and particularly 
disgusted that the most practical solution is ditching the whole 
thing and doing it in PowerPoint). Adobe invented PostScript. Adobe 
invented PDF as a derivative of PostScript. Adobe created Acrobat. 
The whole point of vector graphics is that they're scalable and 
resolution independent. Is there some reason Adobe is unclear on this 
concept? I understand that gracefully rendering at everything from 
72dpi to 12000dpi is non-trivial, but other apps can handle it and 
Adobe of all things is renowned for it.

Uh, yeah... 8^P. This is where you lose me. I have work to do. 
Preview.app and flipping PowerPoint can take these graphics /as is/ 
and render them beautifully. Wasting time fiddling with every one of 
my graphics to work around bugs in Acrobat just ain't going to 
happen. If it were just one logo (which is no longer used (it was a 
one-year thing)), no big deal, but every figure I generate has this

Cool, I'll look into it.
