/*
* GFLI 1.3
*
* A pika plug-in to read and write FLI and FLC movies.

*
* This is a first loader for FLI and FLC movies. It uses as the same method as
* the gif plug-in to store the animation (i.e. 1 layer/frame).
*
* Current disadvantages:
* - Generates A LOT OF warnings.
* - Consumes a lot of memory (See wish-list: use the original data or
* compression).
* - doesn't support palette changes between two frames.
*
* Wish-List:
* - I'd like to have a different format for storing animations, so I can use
* Layers and Alpha-Channels for effects. An older version of
* this plug-in created one image per frame, and went real soon out of
* memory.
* - I'd like a method that requests unmodified frames from the original
* image, and stores modified without destroying the original file.
* - I'd like a way to store additional information about a image to it, for
* example copyright stuff or a timecode.
* - I've thought about a small utility to mix MIDI events as custom chunks
* between the FLI chunks. Anyone interested in implementing this ?
*/
/*
* History:
* 1.0 first release
* 1.1 first support for FLI saving (BRUN and LC chunks)
* 1.2 support for load/save ranges, fixed SGI & SUN problems (I hope...), fixed FLC
* 1.3 made saving actually work, alpha channel is silently ignored;
loading was broken too, fixed it --Sven
