The PLplot development team have just implemented a demanding 2D rendering test for X where we modify our standard example 27 (see http://plplot.sourceforge.net/examples.php?demo=27). The standard version of that example simply draws a line corresponding to increasingly more complex "spirographic" polygons. We have modified that example to fill using those boundaries with some really strange results. The rendering is awful (many missing filled areas and/or areas filled when they shouldn't be) for all spirographic cases if I use the EvenOddRule fill rule. If I use the WindingRule instead, the results are more acceptable although there are still some obvious fill issues for the case of the more complex spirographic boundaries.
The first obvious question is where should I report these X stack fill bugs? Does the X server handle all fills (so these issues should be reported/discussed on the X list) or does the driver (or some other component of the X stack) do the fills (in which case the discussion should obviously be here since I am using the Intel X stack (Debian Squeeze version).
