What is happening:
From a stand-still, your pony will move in an unintended direction during a jump.

What should be happening:
The desired trajectory would be nice

Steps to reproduce the issue:

1. Jump from a standstill.
2. Move (AWSD) in any direction.

Notes: the resulted movement can actually be unpredictable. Sometimes the pony will move according to where they are facing (during mid-air move attempt), sometimes they won't be able to gain movement at all while in air.
This may be due to a kind of input lag. Can't determine if due to slow machine, since FPS remains nominal--but it is noticeably harder to Jump in lower-FPS conditions. It is generally difficult to jump in succession in all situations, though.
