FLIF Suggestions

[Luminous]

Add options for controlling Lossy compression.

Ensure that FLIF properly saves as 16bits/channel if the original image format is 16bits/channel.

Fast Decode Option for large images. I noticed that 4096x4096px FLIF files take on average, 6 times longer to display than a PNG with max lossless. That's a problem. One of the potential benefits of using FLIF over PNG is for storing large files in a much smaller format. To give an example, a 78MB PNG was compressed down to 11MB when using FLIF. That's a pretty massive savings. The problem that occurred afterwards, is the FLIF file took nearly 6x longer to display, which in my opinion, negates the advantage of using FLIF for high resolution files.

Display whether a FLIF is Lossy or Lossless in the status bar of XNView.

That's all I can think of for now.

Thanks!
