Rodolfo Osvaldo Bogado 9e2bbec47f a lot of modifications here :) 
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.
