◆ CanOffsetClips()

bool WaveTrack::CanOffsetClips	(	const std::vector< WaveClip * > &	clips,

Decide whether the clips could be offset (and inserted) together without overlapping other clips.

Returns: true if possible to offset by (allowedAmount ? *allowedAmount : amount)

Parameters

	clips	not necessarily in this track
	amount	signed
[out]	allowedAmount	if null, test exact amount only; else, largest (in magnitude) possible offset with same sign

MM: Now that each wave track can contain multiple clips, we don't have a continuous space of samples anymore, but we simulate it, because there are a lot of places (e.g. effects) using this interface. This interface makes much sense for modifying samples, but note that it is not time-accurate, because the "offset" is a double value and therefore can lie inbetween samples. But as long as you use the same value for "start" in both calls to "Set" and "Get" it is guaranteed that the same samples are affected.

    //   This resembles the old (pre-multiclip support) behaviour. However, if
    //   the clip is pasted outside of any clip, a NEW clip is generated. This is
    //   the only behaviour which is different to what was done before, but it
    //   shouldn't confuse users too much.
    //
    // - If multiple clips should be pasted, or a single clip that does not fill
    // the duration of the pasted track, these are always pasted as single
    // clips, and the current clip is split, when necessary. This may seem
    // strange at first, but it probably is better than trying to auto-merge
    // anything. The user can still merge the clips by hand (which should be a
    // simple command reachable by a hotkey or single mouse click).
