GRF container format 2, NFO version 32, extra zoom and 32bpp graphics
Today we released a new major release of GRFCodec. The major feature of this release is the support for 32bpp and extra zoom graphics. This required changes in the GRF container format and the NFO, so both got an overhaul as well. GRF container format 2 allows much bigger (pseudo) sprites and NFO v32 makes it possible to add multiple real sprite to a 8bpp sprite. Finally the -n option for GRFCodec tries to find the smallest compression yielding slightly smaller GRFs.
