First a bugfix:

Browse Source 
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.
