GZDoom reaches `V_Init: allocate screen` with its GL 4.6.0 context on an even modeNum.

Window and screen -pixels are still the wall: the direct-GL payload VAs (the `0x4001004` setup -push and the `0x4250000`/`0x4250110` draws) resolve to zero/implausible PAs -because their user/UVM VAS is never registered, so its draws never reach the -engine; glxgears' window is black, and X screen-init keeps a per-boot -first-generation lottery.

Window and screen pixels are still the wall: +the MME macro program does not complete (the 2799-word packed program cannot +fit its <=2048-word block with the draw window, so `live_gen` never promotes +and the draw never stores; the multi-part keep-window A/B is pending), RT +routing was tested and refuted as the cause, glxgears' window is black, and X +start keeps a per-boot first-generation lottery.
