25 __OPENGLESHEADERS_LEGACY_EGL_1_1 |
|
26 |
|
27 The purpose of this define is to allow the staged migration to |
|
28 EGL 1.3 from EGL 1.1 taken from the perspective of OpenGL ES 1.X |
|
29 |
|
30 If __OPENGLESHEADERS_LEGACY_EGL_1_1 is defined, then GLES/egl.h and |
|
31 GLES/egltypes.h will only provide the EGL 1.1 API; in particular no |
|
32 symbols from a later version of EGL will be seen at a source code level. |
|
33 This is considered to be legacy behaviour. If |
|
34 __OPENGLESHEADERS_LEGACY_EGL_1_1 is not defined, the GLES/egl.h |
|
35 and GLES/egltypes.h header files will re-direct to the system-wide |
|
36 EGL/egl.h. and EGL/egltypes.h respectively. |
|
37 |
|
38 The use of GLES/egl.h or GLES/egltypes.h by applications is considered |
|
39 legacy behaviour because applications should instead use EGL/egl.h |
|
40 or EGL/egltypes.h respectively. |
|
41 |
|
42 When this legacy behaviour is desired, the define should be placed in an |
|
43 OEM-specific system-wide .hrh file. Symbian product configurations |
|
44 never set this legacy behaviour. |
