HUGE commit :)

in general cleanup and bugfix disable pierre  patch for the moment as it causes problem in some games and hopefully fix the remaining missing textures for nvidia users in opengl.
make the code in pixelshadergen looks nice and readable.
D3D: this is a ultra experimental commit please check for regressions or error.
make the efb Scale / super sampling level customizable to improve the output quality and let the user configure quality according to his hardware.
is everyone likes this change will translate it to opengl
please test
