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