it’s in glext.h among the GL_APPLE_texture_range extension.
#if GL_APPLE_texture_range
#define GL_TEXTURE_RANGE_LENGTH_APPLE 0x85B7
#define GL_TEXTURE_RANGE_POINTER_APPLE 0x85B8
#define GL_TEXTURE_STORAGE_HINT_APPLE 0x85BC
#define GL_TEXTURE_MINIMIZE_STORAGE_APPLE 0x85B6
#endif
This extension was never registered with the OpenGL Extension Registry at http://oss.sgi.com/projects/ogl-sample/registry/ so it isn’t in any header files except Apple’s. I don’t mind adding it to JOGL’s glext.h, but could you please file an Issue and attach the relevant portions of the header file? Thanks.
