When requested, JIT render mode will be used if the display server supports it. Otherwise, a warning is generated instead. This essentially uses the signalNextFrame logic for imgui, but for everything. We automatically enable this mode when overlay is on. Currently, this exposes some damage tracking bugs in the EGL renderer.
