Contexts

#include <eglplus/context.hpp>

Context is a wrapper around EGLContext.

Context attributes

typedef AttributeList<ContextAttrib, ...> ContextAttribs; 

typedef FinishedAttributeList<ContextAttrib, ...> FinishedContextAttribs;

	Attribute list type for context attributes.
	Finished attribute list type for context attributes.
