// Metroids text issue (character table):
// Same addr, same GX_TF_C4 texture data but different TLUT (hence different outputs).
// That's why we have to hash the TLUT too for TLUT tex_format dependent textures (ie. GX_TF_C4, GX_TF_C8, GX_TF_C14X2).
// And since the address and tex data don't change, the key index in the cacheEntry map can't be the address but
// have to be a real unique ID.
// DONE but not satifiying yet -> may break copyEFBToTexture sometimes.
// Pokemon Colosseum text issue (plain text):
// Use a GX_TF_I4 512x512 text-flush-texture at a const address.
// The problem here was just the sparse hash on the texture. This texture is partly overwrited (what is needed only)
// so lot's of remaning old text. Thin white chars on black bg too.
// TODO: - clean this up when ready to kill old "unsafe texture cache"
// - fix the key index situation with CopyRenderTargetToTexture.
// Could happen only for GX_TF_C4, GX_TF_C8 and GX_TF_C14X2 fmt.
