 This patch gives a small performance boost in drawing screens, especially
 the Watch Recordings screen, leading to slightly improved responsiveness.

 The issue is that certain images may be loaded dozens if not hundreds of
 times, and even if the image is already in the cache, a stat system call
 is still performed to see if the original file has changed.  These system
 calls can add up, especially on network file systems.

 The new code relaxes the check on the original file so that the check
 isn't repeated if it was already done within the past 5 seconds.
