file converter for .photon, .photons, .pws and .cbddlp full support for AA (if the format supports it) with grayscale preview.
preview images get replaced by something arbitrary currently as scaling between the different sizes is not implemented yet.
The converter uses an internal format that can easily be used with other js projects for impoert/export
an online copy is hosted over at http://converter.chrisgraf.de/
photon import based on Rob2048's photon file import script.
