> We need to:
>   * Add an API in {{MosaicImageWriter}} for applying an operation on the source tiles, before to write the target tiles
>   * Add a convenience method defining an operation for making border transparent. This operation would be based on the "{{SilhouetteMask}}" image operation.
>   * Get MosaicImageWriter to cache the result of that operation in temporary file will building the mosaic.
>   * Add a panel in {{MosaicWizard}} for selecting the border color to make transparent, and give the selected colors to the above API.
