And make it the default. In libplacebo, this uses internal heuristics to pick a good size based on the actual ICC characteristics. This is significantly less wasteful than always generating a 64x64x64 3DLUT (the old status quo). In vo_gpu, for simplicity, just default to 65x65x65. Note that this provides slightly better accuracy than the old default of 64x64x64 for technical reasons, and matches what libplacebo defaults to for typical display profiles.
