Suppress freestyle sound when performing a glissando in 3d mode

[dtinth]

Changelog

When playing in 3D mode (e.g. using a touch screen), performing a fast glissando between 2 notes with one column of gap in-between will no longer emit the sound of the gap. For example, given a note pattern 1-3-5-7, you can swipe your finger from 1~7, and the game will suppress the sounds of column 2-4-6. This improves the playing experience in mobile devices.
