/* notes (about "safe texture cache"):
* 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 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.
