Debug

• Dump GL cmds on b2g

  adb shell setprop debug.egl.trace 1
  adb shell stop b2g
  adb shell start b2g

P.S. With above property, logcat outputs lots of gl cmds but it is possible that some gl cmds are lost or disorder.

    It is better to compare with gecko's GL wrapper log(You can only print the API you want to trace)

• Dump Layout/Layer tree(layer_layout.patch)
  • Apply gfx/* for Layer Tree
  • Apply layout/ for Layout

• Dump frame tree on gdb
  • add the following changes in layout/generic/nsFrameList.h and rebuild gecko

 #define DEBUG_FRAME_DUMP 1

• • call DumpFrameTree on gdb

  (gdb) p aForFrame->DumpFrameTree()
