Work round the problem that when setting ProcessTimeUnits to a large value, the perfo

Synopsis:

  Work round the problem that when setting ProcessTimeUnits to a large value, the performance will be impacted very much.

   

Overview:

When setting ProcessTimeUnits =1, thumbnail feature will not always work, so we should set ProcessTimeUnits to a large value, but for some streams, it will blt several times, and impact performance very much, so we work round this problem by stopping bltting if we found the frame have been bltted.

  The work round solution will work only when doing thumbnail, we use SetOption to get known whether we are doing thumbnail.
