Whew. You know how you sit there, looking at your working code, thinking "I'm so glad it works. It works really well! But… it could be better… I wonder if instead of a bitmap I could get resolution independent ouput?"

Well, just stop. Go for a walk. Watch a movie. Whatever you do, do NOT take a few minutes to find that little bit of code that will give you resolution independent output. Do NOT spend the little-less-than-an-hour it takes to convert your bitmap generating code over to, oh-goodness-it's-sweet-high-quality-PDF…

Do NOT sit for two hours trying to understand why someone thought it would be a good idea to have the drawing code work opposite the global coordinate system, leaving your cleverly written code to flounder while the oh-goodness-it's-sweet-high-quality-PDF output runs right off the page in a fit of un-coordinate-d rage…
