+SYMBIAN_EGLHEADERS_API_VERSION_1_4
+
+This macro introduces the declaration of version 1.4 of EGL.  It is
+mutually exclusive with the macro SYMBIAN_EGLHEADERS_API_VERSION_1_3
+and SYMBIAN_EGLHEADERS_API_VERSION_1_2
+
+Symbian component "eglinterface" provides the declared interface for EGL
+Symbian component "eglimplementation" provides a reference implementation of EGL
+
+EGL implementations enable the provision of the following APIs which
+sit on top of EGL; the choice of *those* APIs therefore governs the version
+of EGL needed.  Newer versions of EGL are binary compatible with older versions
+of EGL so that newer EGL versions support the APIs supported by previous EGL
+versions.  Newer versions of EGL are source compatible with older EGL versions
+apart from the fact that newer EGL versions introduce new tokens as #defines
+and also specify the version of the EGL API in a #define.  This means that
+applications written to detect such #defines could have modified behaviour
+after a re-compile.
+
+EGL 1.4 Allows control of swap behavior (preserving back buffer contents) using
+the EGL_SWAP_BEHAVIOR bit in the EGL_SURFACE_TYPE EGLSurface attribute.
