TfrxPictureView memory usage

  Just tried it:
  - create an empty report;
  - put a TfrxPictureView on the databand;
  - load a picture into it;
  - set databand.RowCount to 1000 to repeat it 1000 times;
  - run the report.
  You will see the report generates immediately and takes a little amount of memory.

  Hi Alex,
  
  Thanks for looking into this. You have to preview the report and step through the pages. I did the same thing as you - image on a band repeated 1000 times. I then stepped through the preview one page at a time and got this error on page 11:

  Debugger Exception Notification

  Project Project1.exe raised exception class EOSError with message 'System Error. Code: 8.
  Not enough storage is available to process this command'.

  It was a large image (4MB), but it happens with smaller images as well - it just takes more pages. I tried the UseFileCache option but it didn't help.
  
  I assume it is caching preview pages or something like that. Is there a way I can force it to cache less pages to prevent this kind of problem?
  
  Thanks,
  Pierre

  Normally FR caches 50 preview pages. I can add a parameter to PreviewOptions that handles this.
  
  + added TfrxReport.PreviewOptions.PagesInCache property

  Hi Alex,
  
  Yes, I agree - that will be a very useful option to have.
  
  Thanks,
