+ * The user may select, for window surfaces, the EGL_RENDER_BUFFER through
+ * the attribute list of eglCreateWindowSurface(). The EGL spec allows the
+ * implementation to ignore request, though; hence why we maintain both
+ * RequestedRenderBuffer and ActiveRenderBuffer. For pbuffer and pixmap
+ * surfaces, the EGL spec hard-codes the EGL_RENDER_BUFFER value and the
+ * user must not provide it in the attribute list.
+ *
+ * Normally, the attribute is immutable and after surface creation.
+ * However, EGL_KHR_mutable_render_buffer allows the user to change it in
+ * window surfaces via eglSurfaceAttrib, in which case
+ * eglQuerySurface(EGL_RENDER_BUFFER) will immediately afterwards return
+ * the requested value but the actual render buffer used by the context
+ * does not change until completion of the next eglSwapBuffers call.
+ *
+ * From the EGL_KHR_mutable_render_buffer spec (v12):
+ *
+ * Querying EGL_RENDER_BUFFER returns the buffer which client API
+ * rendering is requested to use. For a window surface, this is the
+ * attribute value specified when the surface was created or last set
+ * via eglSurfaceAttrib.
+ *
+ * eglQueryContext(EGL_RENDER_BUFFER) ignores this.

+ * eglQuerySurface(EGL_RENDER_BUFFER) ignores this.
+ *
+ * If a window surface is bound as the draw surface and has a pending,
+ * user-requested change to EGL_RENDER_BUFFER, then the next eglSwapBuffers
+ * will flush the pending change. (The flush of EGL_RENDER_BUFFER state may
+ * occur without the implicit glFlush induced by eglSwapBuffers). The spec
+ * requires that the flush occur at that time and nowhere else. During the
+ * state-flush, we copy RequestedRenderBuffer to ActiveRenderBuffer.
+ *
+ * From the EGL_KHR_mutable_render_buffer spec (v12):
+ *

+ * attribute, eglSwapBuffers performs an implicit flush operation on the
