  Capture/Replay: Multi-Context Support
  
  Add support for capturing and replaying multiple contexts.
  
  1.) Create and initialize the Contexts in the share group during
  SetupReplay().
  2.) Track the Context the command stream is for, and if the Context ID
  changes, inject an eglMakeCurrent() call to switch to the new Context.
  3.) Intercept eglCreateContext() and eglMakeCurrent() to route to either
  EGLWindow or WGLWindow, depending on the current platform.
  
  Specifically, this enables capturing and replaying Asphalt 9.
