dolphin/Source/Plugins/Plugin_VideoOGL/Src/TextureMngr.cpp
Rodolfo Osvaldo Bogado 02189ec5e0 Simplify the params for the safe texture cache 
after some test the more relevant parameters were the color samples and the tlut max size.
so delete the rest of the parameters and define 3 modes:
Safe : the two values are set to 0 meaning all the texture data and all the tlut data are hashed this is the most correct and slowwwwwwwwwww way
Normal: 37 samples are taken from the color textures an the firs 4096 bytes of the tlut are hashed, is a lot faster than safe mode but in some games i observe small glitches.
Fast: 8 samples are taken from the color textures an the first 1024 bytes are hashed from the tlut, is a little slower than the unsafe cache but at least all the games i tested have correct text output and fast frame rate. the glitches in dinamyc color textures are more noticeable in this mode
this values could be improved, if you find a better combination please post it and the game it fixes and i will update the source.
for the moment, as my time is limited by a lot of work, only implemented the d3d gui, if someone can implement the opengl gui will be a lot of help for me.
please test a lot and let me know the results.

// 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.
