Subject: MouseInput: invert y-accel property
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=8a08507282941e6dd6dfccf63e3356f87e6d0114;p=flightgear.git

MouseInput: invert y-accel property

Syd Adams:  It could be inverted with nasal for use,
but it feels more natural with positive /forward , negative /
back.
