Issue description
I have noticed a number of issues in the Mandlebrot fractal images sample:

1) the GUI startup size is fixed (always the same) when it should be computed according to the configured image dimensions

2) the progress/wait bar never appears, except for the first image computation when replaying a record set. For individual computations, I ever see it.

3) when trying to save a recordset, the specified file is not created and the log shows the following exception:

Fixed in: While I was at it, I also implemented an API to create and use custom mouse cursors, so now the cursor changes to a crosshair-like cursor when hovering over the image.
