title: Draw a circle with a specific number of pixels
body: <p>I'm working on a project that requires me to accurately control the number of pixels that are used to draw (roughly) circular stimuli, and although Bresenham's algorithms are great, they don't draw circles of an arbitrary area (to my knowledge).  I've tried scripts that interrupt Bresenham's algorithm when the desired area has been plotted, but the results are decidedly hit-or-miss.  Does anyone know of a way to plot the "best" circle (somewhat subjective, I know) using a given number of pixels?  Many thanks!  </p>
