Photoshop "Display Info" Decoding

i can hack the source, but a first step would be to change the name collision in Photoshop.pm:

    0x03ef => { Unknown => 1, Name => 'DisplayInfo' },
    0x0435 => { Unknown => 1, Name => 'DisplayInfo' }

0x03ef is obsolete and effectively replaced by 0x0435.  i recommend leaving 0x03ef as is, but changing 0x0435 to "ChannelOptions" - as that is exactly what it is (see attached).

this is important metadata, as it informs programmatic interactions with alpha channels in PSD files.

i'm almost done decoding it, will share soon.  - J
