// The root cause of this bug was that a stroked arc with round caps was batched with a filled
|
|
// circle. The circle op code would choose a GeometryProcessor configuration that expected round
|
|
// cap centers as vertex attributes. However, the tessellation code for the filled circle would
|
|
// not put in zero-width round cap centers and then didn't advance the pointer into which
|
|
// vertex data was being written by the expected vertex stride.
