    1.32 +This macro introduces the declaration of version 1.4 of EGL.  It is
    1.33 +mutually exclusive with the macro SYMBIAN_EGLHEADERS_API_VERSION_1_3
    1.34 +and SYMBIAN_EGLHEADERS_API_VERSION_1_2
    1.35 +
    1.36 +Symbian component "eglinterface" provides the declared interface for EGL
    1.37 +Symbian component "eglimplementation" provides a reference implementation of EGL
    1.38 +
    1.39 +EGL implementations enable the provision of the following APIs which
    1.40 +sit on top of EGL; the choice of *those* APIs therefore governs the version
    1.41 +of EGL needed.  Newer versions of EGL are binary compatible with older versions
    1.42 +of EGL so that newer EGL versions support the APIs supported by previous EGL
    1.43 +versions.  Newer versions of EGL are source compatible with older EGL versions
    1.44 +apart from the fact that newer EGL versions introduce new tokens as #defines
    1.45 +and also specify the version of the EGL API in a #define.  This means that
    1.46 +applications written to detect such #defines could have modified behaviour
    1.47 +after a re-compile.
    1.48 +
    1.49 +EGL 1.4 Allows control of swap behavior (preserving back buffer contents) using
    1.50 +the EGL_SWAP_BEHAVIOR bit in the EGL_SURFACE_TYPE EGLSurface attribute.
