	//	Have to be removed soon.
	//	But we keep it until the "safe" way became rock solid
	//	pros: it has an unique ID held by the texture data itself (@address) once cached.
	//	cons: it writes this unique ID in the gc RAM <- very dangerous (break MP1) and ugly 

	// 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 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.
	//			Wonder if we can't use tex width&height to know if EFB might be copied to it...
