        returns 1 if the cue point has passed and 0 if it hasn't been passed. 
        For example, if <code><font color="#666666">cuePointID</font></code> is 
        2, then <code>isPastCuePoint</code> will return 1 if the second cue point

<font face="Geneva, Arial, Helvetica, sans-serif" size="-1">The number returned by </font><code>isPastCuePoint</code><font face="Geneva, Arial, Helvetica, sans-serif" size="2"> is based on the absolute position of the sprite in the QuickTime movie.

<font face="Geneva, Arial, Helvetica, sans-serif" size="-1">When the result of </font><code>isPastCuePoint</code><font face="Geneva, Arial, Helvetica, sans-serif" size="2"> is treated as a Boolean value, the function returns </font><code>TRUE</code><font face="Geneva, Arial, Helvetica, sans-serif" size="2"> if any cue points identified by </font><code>cuePointID</code><font face="Geneva, Arial, Helvetica, sans-serif" size="2"> have passed, and </font><code>FALSE</code><font face="Geneva, Arial, Helvetica, sans-serif" size="2"> if no cue points are passed. </font>
