[PATCH v2 0/2] MR8216: server: prevent division by zero in coordinate mapping

[Wei Xie (＠wayne)]

Wine applications crash in VNC/headless environments due to invalid all-zero monitor coordinates.

The root cause is:
- Environment Issue: VNC systems report all displays as RR_Disconnected
- Faulty Fallback: Wine incorrectly reverts to legacy XRandR 1.0 API when no "connected" displays are detected
- API Incompatibility: Modern XRandR 1.6 doesn't support Wine's XRandR 1.0 implementation, causing XRRSizes() to return empty display modes
- Uninitialized Data: This leaves critical display fields (dmPelsWidth/Height) at initialization value 0
