It's worth noting that I made a conscious decision to keep the name of the existing non-stroked benchmarks the same rather than prefix them with "closed_" in order to keep them connected to their history of measurements in the perf tracker. I could be swayed that having them be named more specific to their closed version of the path data is more important than the historical trends if reviewers think otherwise... |

The stroking benchmarks were using source paths that were completely closed which means that they were never testing the performance of stroke caps since none would be generated while widening the paths.
All stroking benchmarks are now run against unclosed versions of the paths to provide a mix of caps and joins in the measurements, and the non-stroking benchmarks are now also run against unclosed versions of the paths to add more measurements using the newly available test path data.
This change will affect all of the geometry benchmarks named "stroke_[Curve type][Cap][Join]". The Round and Square cap benchmarks will be the most affected and for the worse.
