This evening while hanging out at our neighbor's house this dragonfly decided to land on my leg and hang out. After it became clear he wasn't flying away with everyone looking at him I tried to motivate him with my finger, whereupon he crawled onto it. This became a novel moment and my wife grabbed the camera and I took some shots while he hung out.

This program demonstrates how non-uniform scaling the CTM can adversely affect line rendering performance. It draws a grid of lines with scaling in X and Y adjustable by sliders and a rotate slider to get feedback on how fast it can render.

This is two lines, one is solid black and the other is red and dashed, both 100pts wide, same end points. When the line join style is set to bevel and the ctm is rotated the dashes are overzealously clipped by CoreGraphics. The dashes should continue all the way up to the top as the black line does. It will also show up if the miter limit is zero which effectively uses bevel joins.
