9601a2 breaks rotations

[LaserEyess]

After commit 9601a2a my rotated monitor no longer works, reverting the commit fixes this issue.

Relevant config section:

output DP-1 {
    pos 0 0
    res 2560x1440@144Hz
    adaptive_sync on
}
output DP-2 {
    pos 2560 -500
    transform 270
    res 2560x1440@144Hz
    adaptive_sync on
}
output DP-3 {
    pos 4000 -200
    res 3840x2160@60Hz
    adaptive_sync on
    scale 2
}

DP-2 is affected, DP-1 and DP-3 are not. Will try to reproduce with a clean config.

Can repro as well. Some notes:

• Only repros with 90 and 270. 180 is fine.
• Everything looks fine when the resolution is a square (width == height), so probably width and height need to be swapped somewhere.

On a clean config with nothing except those transforms, I can still reproduce it and as emersion says only 90/270 are affected.
