Added optional padding to video frames because that's what VideoPlayerWidget expects.
Keeping the option to not use padding for other use-cases like converting frames to PNG.
Removed property backing fields where applicable, introduced C#7 syntax for properties.
Renamed a bunch of interface properties and class private members with more descriptive names.
Did some inconsequential reordering.
- Fixed a rounding issue in `WavReader.WaveLength()`.
- Fixed `AudReader.SoundLength()` not resetting the stream position.
- Fixed crashes caused by disposed streams because `LengthInSeconds` would try and calculate the length on the fly. It is now precalculated and cached (making it consistent across all 5 current `ISoundFormat` implementations).
- Fixed a crash in `AudReader.LoadSound()`'s `out Func<Stream> result` because that func would try and access the disposed stream's `Length` property. That works for `SegmentStream`, but not for `FileStream`.
- Fixed frameCount/soundLength label positioning in the AssetBrowser window to avoid text clipping .
* TSVeinsRenderer now shows border cells on the radar
* BuildableTerrainLayer now uses the radar colors defined on the individual tiles
* CliffBackImpassabilityLayer no longer overrides the underlying terrain color.
While they may be only 'visual' in terms of influence/cell grid,
they all do update CenterPosition, which is essentially the
actual world position of the actor.
'Visual' would imply that it only affects the position where the
actor is drawn, which is inaccurate.
Furthermore, using the term 'Visual' here would make
naming future methods/properties related to visual interpolation
unnecessarily complicated, because that's where we might
need a real 'Visual(Only)Position'.
Alpha can specify a single value for the sequence
or values for each frame in the sequence.
AlphaFade: True can be specified to linearly fade
to transparent over the length of the animation.
