CoerceMode -- calculate ViewPort mode coercion (V39)
ID = CoerceMode(RealViewPort, MonitorID, Flags);
d0 a0 d0 d1
ULONG CoerceMode(struct ViewPort *, ULONG, ULONG);
To determine the best mode in the MonitorID to coerce RealViewPort to,
given the restrictions set in Flags.
RealViewPort - ViewPort to coerce
MonitorID - Montor number to coerce to (ie a mode masked with
MONITOR_ID_MASK).
Flags - PRESERVE_COLORS - keep the number of bitplanes
in the ViewPort.
AVOID_FLICKER - do not coerce to an interlace mode
ID - ID of the best mode to coerce to, or INVALID_ID if could not
coerce (see NOTES).
This function takes into account the compatibility of the Monitor
being coerced to, and the ViewPort that is being coerced.
Incompatibilities will cause a result of INVALID_ID.
newmode = CoerceMode(vp, VGA_MONITOR_ID, PRESERVE_COLORS);
