37 /* differences from the actual sample implementation provided by Khronos:
39 - the Doxygen comment with tag 'publishedAll', and tag 'released'
40 - changing platform-dependant header name from <EGL/eglplatform.h> to <EGL/egltypes.h>
41 - EGLImageKHR definition is consistent with other EGL objects, i.e. is defined as integer
42 instead of pointer to void.
43 - macro EGL_IMAGE_PRESERVED_SYMBIAN introduced in this header represents EGL_IMAGE_PRESERVED_KHR
44 macro defined in Khronos spec. Note that it has been retained temporarily for compatibility reasons
45 and it is advised to use Khronos macro instead.
46 - resource profiler and reusable sync object extensions are added
