thanks for the comments in the prev commit they make my re think the approach.

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.

fixed a misbehavior in the clear code that causes depth clear problems in reference hardware (Intel as example).
add 6 parameters to optimize Safe Texture Cache:
SafeTextureCacheColorSamples, SafeTextureCacheIndexedSamples, SafeTextureCacheTlutSamples:

this 3 parameters gives the number of samples taken to calculate the final hash value, less samples = more speed, more samples = more accuracy
if 0 is specified the hash is calculated using all the data in the texture.
SafeTextureCacheColorMaxSize, SafeTextureCacheIndexedMaxSize, SafeTextureCacheTlutMaxSize:
this parameters limits the amount of data used for the hash calculation, it could appear as redundant but in some games is better to make a full hash of the first bytes instead of some samples of all the texture.

color, indexed, tlut : define the texture type, full color data, indexed, and the tlut memory.

the parameters are available in the config , no GUI at this time, if the test are OK will add it to the GUI.
if someone needs it will give more examples on how to configure the values for specific games.

sorry to tell but this will bring a speed drop, so let you decide if this change stay or not.( used the fastest open source hash algorithm i know) 
do not apply full hashing to other format because it kills the performance.
for popular request added 9x SSAA believe me will kill your graphic card even if is the best but the image quality is exceptional.
as always please test and let me know the results.

reverted a tiny leftover of my safe texture cache commit
D3D
renamed the SSAA modes to use samples as MSAA now they are 2,25x and 4x.
OpenGL:
fixed a nasty logical bug introduced in 4984 that causes efb corruption when efb to texture is used
re enabled shader caching as it was not producing errors.
fixed efb misalignment caused by integer rounding still a bit misaligned but many games will look better now

first fixed scaling when updating backbuffer to make it friendly with encoders, now frame dumping must work without errors in any codec.
clean screenshot and frame dumping code now is more correct, faster and stable.
improve safe texture cache, improving the distribution of the hash algorithm, including tlut hash in the final hash of the texture, and making use of a 64 bit hash to make it more accurate.
clean a lot of code and corrected some missused vertex formats when drawing full screen quads.
and biggest change last:
implemented pseudo antialiasing: a image post-process algorithm that mimics antialiazing and is fare more easier to implement in this scenario.
you can change the intensity of the effect changing the values of the antialiasing combo. the right value depends on the game.
for example mkwii looks awesome with 8x.
please try all the changes and let me know the results.
if something is broken, please let me know and will fix it asap.

Basic usage:  "sudo scons install=global install"
Hopefully this doesn't break builds on Macs.  I have tested this on linux and windows.

in D3D and Opengl:
fixed one nasty bug in texture loading where if a dynamic texture keeps his format but the tlut format is changed, the try or reloading the texture in the same texture could cause a hang if the size of the resulting texture is different than the original (size in bytes)
Applied a ugly temporal hack to the texture conversor to solve efb to ram misalignments and effect distortions.
in D3D:
Pseudo implementation of logic ops using basic blending: the first 8 operations are "good approximations", the remaining 8 are bullshit :) if someone have a better approximation to emulate this logic please let me know.
please test if i don't break anything in the process and test Mario kart wee you will get a nice surprise.:)
