/*
* gifio_reg.c
*
* This tests reading and writing gif for various image types.
*
* The relative times for writing of gif and png are interesting.
*
* For 1 bpp:
*
* png writing is about 2x faster than gif writing, using giflib.
*
* For 32 bpp, using a 1 Mpix rgb image:
*
* png: Lossless: 1.16 sec (2.0 MB output file)
* Lossy: 0.43 sec, composed of:
* 0.22 sec (octree quant with dithering)
* 0.21 sec (to compress and write out)
*
* gif: Lossy: 0.34 sec, composed of:
* 0.22 sec (octree quant with dithering)
* 0.12 sec (to compress and write out)
* (note: no lossless mode; gif can't write out rgb)
