+/* This test case is designed to illustrate a performance bug that
+ * exists in cairo in which using cairo_stroke is much slower than
+ * cairo_fill to draw an identical figure, (and in particular a figure
+ * that is much more natural to draw with cairo_stroke). The figure is
+ * a 100x100 square outline 1-pixel wide, nicely pixel aligned.
+ *
+ * The performance bug should affect any path whose resulting contour
+ * consists only of pixel-aligned horizontal and vertical elements.
+ *
+ * Initial testing on on machine shows stroke as 5x slower than fill
+ * for the xlib backend and 16x slower for the image backend.
