#calculationPurpose (predefined symbol)
This predefined symbol returns a value that indicates the purpose for which the current calculation is used. A formula can change its behavior depending on this value. For example, you could use a higher-quality but slower calculation when rendering.
Possible values are:
|0||Normal: the formula is used by a regular fractal window|
|1||Thumbnail: the formula is used by the browser to show thumbnails|
|2||Render: the formula is used by the disk rendering engine to produce a high-quality final image|
|3||Live preview: the formula is used for a live preview image in the Fractal Mode tool window (when exploring, eyedropping, or switching)|
if #calculationPurpose == 2 ; Formula is used in a disk render operation else ; Normal fractal window or thumbnail/preview calculation endif
