Add encoder for AMD decoder #4

Closed castano closed 2 years ago

castano commented 4 years ago

Every IHV decodes DXT blocks in a slightly different way. It would be good to have a specialized encoder to target each IHVs specific decoder. This would be particularly useful for console titles whose assets would run on a specific platform.

In 1.04 you can now specify the target hardware decoder through the init_dxt1 function. Currently this only affects the optimal single color encoder and the index selection. In the future I'd like to also update the least squares optimizer to take into account the AMD optimization weights.

Done.
