implementations can reuse other implementations (e.g., legacy)
implementations are initialized lazy by strategies
strategy is specified via enum classes of api classes that are using the implementations
(note: implementations should be changed at runtime with care...):
Shader::hintIncludeImplementation(...)
* started placing some using namespace gl in most modified files
* added singleton template to globjects-base that is used for all implementations
refine strategies
