+  Platform integration function for querying the OpenGL implementation type.

+  Used only when dynamic OpenGL implementation loading is enabled.

+  Subclasses should reimplement this function and return a value based on
+  the OpenGL implementation they have chosen to load.
 
+  \note The return value does not indicate or limit the types of
+  contexts that can be created by a given implementation. For example
+  a desktop OpenGL implementation may be capable of creating OpenGL
+  ES-compatible contexts too.
