[gdal-dev] BPG driver

[Even Rouault]

Hi,

For those interested, I've committed an experimental (*) read-only BPG (Better 
Portable Graphics) driver to read the new image format created by Fabrice 
Bellard based on HEVC : http://bellard.org/bpg/
For same quality as JPEG, images are typically twice smaller. Competitor of 
WebP as well, with apparently slightly better quality.
Rather as dealing with standalone images, it could be interested as a codec in 
TIFF for example to benefit from tiling, overviews, etc. Or a GeoPackage tile 
format extension.

Even

(*) No doc, no makefile support at all (libbpg itself is pretty raw). Look at 
frmts/bpg/bpgdataset.cpp to see how to build it as a plugin on Linux.
