After testing out the separated improved zoom mod standalone I found a number of issues resulting from the HD nature of the base mod that caused there to be problems when stock foxhole map was used. Because the stock foxhole map wasn't HD, the aspects of the zoom mod that were made for an HD map completely broke resulting in certain erratic camera zooming.

For this reason I recombined it back into the base mod. White squares are now gone, and zooming should work as it did before with no separate mod needed.
