  ParallelCompile: add GL backend support
  
  For GL backend, at first each worker thread must have a naitve context
  for its own to work in. These worker contexts have to be shared from
  the main context, so that all shader and program objects are seen in
  any context. This extends backend displays to create and destroy the
  worker contexts. RendererGL manages and allocates them to the worker
  threads. ShaderImpl has a new compile method added to do the actual
  glCompile work in worker thread. The ProgramGL's link method is broken
  down by introducing the LinkEventGL class.
