This is a single very long path that results in a large number of line segments when dashing is applied. This demonstrates rendering artifacts.

I'd probably express this case (lines 16-22) in terms of the new addition
Yes of course! This is the expected shape with butt caps: This is the same butt cap render showing artifacts when it's zoomed out: This is the same shape with round caps (which increases the line segment count) showing artifacts at a moderate zoom level: The latter can be fixed by increasing the bump buffer sizes. I'm treating this as a pathological case with a very high memory requirement. The zoomed out case appears regardless of the size of the bump buffers so that's probably a separate issue. |
Added a butt cap and round cap variant of the pathological longpathdash test case. The round caps exhibit the expected increase in the number of line segments post-flattening, and hence a significant increase in required GPU memory. Also added a new `scene!` macro variant for custom test names and factory functions that return a test function.
