@jestarray thanks for the review

@jestarray I'm afraid I reverted this PR, it broke the build because it was incomplete but when reviewing implementation I noticed that gesture should be unsigned int for the flag check agains unsigned int flag:

// Check if a gesture have been detected
bool IsGestureDetected(unsigned int gesture)
{
    if ((GESTURES.enabledFlags & GESTURES.current) == gesture) return true;
    else return false;
}
