HardwareRenderer接口能hook么

问题1.
通过btrace3.0版本抓到的trace，无法展示HardwareRenderer相关的接口，是不支持么？
问题2.
btrace能抓native的火焰图么，为什么抓到的btrace只能看到java层的火焰图，看不到native的火焰图？

No files, tests, or entry points are named. Start by checking the btrace 3.0 trace and documentation for HardwareRenderer and native flame-graph support, then determine whether the missing views are unsupported behavior or a defect. Done means clearly documenting the support status or identifying a reproducible implementation target.
