From a3fb064e000a8706319dc996788159bf84a13f0f Mon Sep 17 00:00:00 2001 From: Emmanuel Gil Peyrot Date: Fri, 8 May 2020 19:23:03 +0200 Subject: [PATCH] Expose EGL_KHR_platform_* when EXT is supported On EGL 1.4, one had to check for the existence of EGL_EXT_platform_base before querying the eglGetPlatformDisplayEXT() and eglCreatePlatformWindowSurfaceEXT() symbols, to then use them if the EGL_EXT_platform_* extension for the given platform was exposed. Since EGL 1.5, the platform functionality was made core, which means we can obtain the symbols unconditionally, but we can't know the EGL version before having created a display, at which point we've already done a platform selection by passing an EGLNativeDisplay. The EGL_KHR_platform_* extensions thus are used by clients to know whether it's safe or not to dlsym() the EGL 1.5 symbols. This commit adds those extensions when the given platform is enabled.
