Remarks

The filter runs on a display list that has already been portrayed, so a host can move the view time without running the portrayal rules again.

The instructions of instructions drawn at time, in order; all of them when time is null.

public static IReadOnlyList<DrawingInstruction> Apply(IReadOnlyList<DrawingInstruction> instructions, PortrayalTime? time)

IReadOnlyList<DrawingInstruction>: The instructions drawn; instructions itself when none is left out.

Whether moving the map from from to to can change what a display list with intervals draws: some interval holds at one and not the other.

public static bool Changes(IEnumerable<PortrayalTimeInterval> intervals, PortrayalTime? from, PortrayalTime? to)

intervals IEnumerable<PortrayalTimeInterval>: The display list's intervals (Intervals(IEnumerable<DrawingInstruction>)).
from PortrayalTime: The time drawn now.
to PortrayalTime: The new time.

The distinct time intervals of instructions, in first-seen order.

public static IReadOnlyList<PortrayalTimeInterval> Intervals(IEnumerable<DrawingInstruction> instructions)

IReadOnlyList<PortrayalTimeInterval>: The intervals; empty when every instruction is always drawn.

Whether instruction is drawn at time: it has no time intervals, or time meets one of them.

public static bool IsDrawn(DrawingInstruction instruction, PortrayalTime time)
