Sending magnification filter info to the sampler
Currently, the magnification filter information is ignored
by SwiftShader. In order to fix it, the 1st step is simply
to make the sampler aware of this information. After this,
a subsequent cl using the duvdxy computed in computeLod
will choose which filter to use (if they are different).
