Previously we imlpemented the standard semantics for eglInitialize / eglTerminate, which are that eglInitialize may be called any number of times, but the first call to eglTerminate will terminate the display. Now we follow reference-countins semantics, which means that eglTerminate will only terminate the display when the reference count returns to zero. This change allows EGL to be used by multiple independently written modules in the same process. (Otherwise there is no way for the independent modules to coordinate their use of the display.)
