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.
