Subject: revert swapping of x & y offsets in "lookat" mode
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=7810fbc632618460dc89a9abfe28de145ed1b2ff;p=flightgear.git

revert swapping of x & y offsets in "lookat" mode
This was correct in the old repository and in revision 1.1 of the new,
but then broken in revision 1.2. After that, "lookat" and "lookfrom"
mode used different coordinate systems, and the "Adjust View Distance"
didn't work correctly in "lookat" mode.
