sl@0: __OPENGLESHEADERS_LEGACY_EGL_1_1
sl@0:     
sl@0: The purpose of this define is to allow the staged migration to
sl@0: EGL 1.3 from EGL 1.1 taken from the perspective of OpenGL ES 1.X
sl@0: 
sl@0: If __OPENGLESHEADERS_LEGACY_EGL_1_1 is defined, then GLES/egl.h and
sl@0: GLES/egltypes.h will only provide the EGL 1.1 API; in particular no 
sl@0: symbols from a later version of EGL will be seen at a source code level.
sl@0: This is considered to be legacy behaviour.  If
sl@0: __OPENGLESHEADERS_LEGACY_EGL_1_1 is not defined, the GLES/egl.h 
sl@0: and GLES/egltypes.h header files will re-direct to the system-wide 
sl@0: EGL/egl.h. and EGL/egltypes.h respectively.
sl@0: 
sl@0: The use of GLES/egl.h or GLES/egltypes.h by applications is considered
sl@0: legacy behaviour because applications should instead use EGL/egl.h
sl@0: or EGL/egltypes.h respectively.
sl@0: 
sl@0: When this legacy behaviour is desired, the define should be placed in an
sl@0: OEM-specific system-wide .hrh file.  Symbian product configurations
sl@0: never set this legacy behaviour.
