The default MaxTimeWeightedRawRows (1,000,000) + 18 exceeded the gateway's default MaxValuesCeiling (1,000,000), so with AllowStreamingBeyondCeiling=false every Gateway per-sample aggregate read was refused. The allowance is now clamped at 1,000,000 while the cap is at or under it (RawAggregateReader. ClampToGatewayCeiling); a cap above it keeps its allowance. Raw reads are not clamped (rebased onto #686).
