GSDX: fixed an oversight in my shader change gregory caught which removed alpha expansion for the direct sampling case, should probably fix the remaining bugs. Also set the texture sampler to point sampling when the shader will be performing its own bilinear filtering (effect on games unknown but should be an improvement).
