williamr@4: __OPENGLESHEADERS_LEGACY_EGL_1_1
williamr@4:     
williamr@4: The purpose of this define is to allow the staged migration to
williamr@4: EGL 1.3 from EGL 1.1 taken from the perspective of OpenGL ES 1.X
williamr@4: 
williamr@4: If __OPENGLESHEADERS_LEGACY_EGL_1_1 is defined, then GLES/egl.h and
williamr@4: GLES/egltypes.h will only provide the EGL 1.1 API; in particular no 
williamr@4: symbols from a later version of EGL will be seen at a source code level.
williamr@4: This is considered to be legacy behaviour.  If
williamr@4: __OPENGLESHEADERS_LEGACY_EGL_1_1 is not defined, the GLES/egl.h 
williamr@4: and GLES/egltypes.h header files will re-direct to the system-wide 
williamr@4: EGL/egl.h. and EGL/egltypes.h respectively.
williamr@4: 
williamr@4: The use of GLES/egl.h or GLES/egltypes.h by applications is considered
williamr@4: legacy behaviour because applications should instead use EGL/egl.h
williamr@4: or EGL/egltypes.h respectively.
williamr@4: 
williamr@4: When this legacy behaviour is desired, the define should be placed in an
williamr@4: OEM-specific system-wide .hrh file.  Symbian product configurations
williamr@4: never set this legacy behaviour.
