Leon Scroggins III 68825776f4 Ensure fSrcOffsetUnits is in a valid range
Bug: oss-fuzz:11114

fSrcOffsetUnits is where we start sampling from the image. It is
computed as

  (sampleX / 2) * fSrcBPP

(ignoring fSrcOffset, which is 0 for a GIF with a subset frame).
sampleX will be no wider than the full image, and we divide it by two to
sample points evenly spread through the image. But for a subset frame,
we need to use a different sampling rate to ensure that the sampled
points are within the width of the frame.
