Previously, the merging strategy is permissive but the lookup strategy is strict. Together they create a infinite merge loop because lookup always fails and merges are always executed.
The last attempt to fix this issue made the lookup strategy more permissive which created unexpected aliased textures.
This commit implements an alternative: make the merging strategy strict.
