Rafał Dzięgiel 04a028d689 plugin: Rework code to use new GL context handler
Create a GL context handler subclass of recently added context handler base class and
rework code to use it. This simplifies a lot of things, like: switching of importers
at runtime, handling context queries, sharing data between importers, etc.
