Simple scene is rendered to the framebuffer 39e5c31af7Sopenharmony_ciobject in such way that all allocated buffers will be exercised. Multisampled 40e5c31af7Sopenharmony_cicolorbuffer contents are then resolved to non-multisampled renderbuffer 41e5c31af7Sopenharmony_ciusing glBlitFramebuffer() and read from there using glReadPixels(). 42e5c31af7Sopenharmony_ci 43e5c31af7Sopenharmony_ciResulting image is compared agaist an image produced by a reference renderer. 44
