Hello,

I've updated PSD coder to make it fastest on 1.3.21.

Previously on "decodeImage", the "GetImagePixels" method was called for each pixels and constantly update the image cache.
Now, 'GetImagePixels' method is called with a pixel range depending on the compressed input.

After few tests, loading time have been reduced from 30 seconds to 5.

Regards,
Demière Cédric.

Testing with 'Banner.psd' from the sample files delivered with Photoshop 7, I find that the original psd.c is able to read the file but fails with "Insuffient data in file" using your updated DecodeImage(). Do you have a fix for this?
