The JS implementation does content hashing to not blit unchanged framebuffer contents (see mihaip/dingusppc@171ff2d407). However, that is not necessary for the ATI adapters that already track this and only set draw_fb if the framebuffer has actually changed. Pass through a fb_known_to_be_changed for these cases, and also add an optional update_skipped method (since the JS still wants to know when the last logical screen update was).
