PlayFetchIndex on a With*Animation trait conflicts with the animation
concept, as it's bound to conflict with pretty much all 'normal'
animation traits and blocks progress on the animation priority system.
We also already have multiple precedent SpriteBody traits of similar kind,
like WithGateSpriteBody and WithWallSpriteBody.
... for looped sequences.
PlayCustomAnimationRepeating looping back into itself via Action instead of simply using Animation.PlayRepeating is weird, and in fact causes a slight 'desync' in animation speed with Animation.PlayRepeating in at least one downstream mod.
The render bounds for an actor now include the area covered
by bibs, shadows, and any other widgets. In many cases this
area is much larger than we really want to consider for
tooltips and mouse selection.
An optional Margin is added to Selectable to support cases
like infantry, where we want the mouse area of the actor
to be larger than the drawn selection box.
Specify pause function in constructors of Animation if required, and remove the unused pause function from AnimationWithOffset.
Cleanup Animation.cs and reduce code duplication.
Moved BodyOrientation and related interfaces from Game to Mods.Common.
Introduced QuantizeFacingsFromSequence trait.
With*Body render traits no longer implement IQuantizeBodyOrientation
themselves.
Extracted AutoSelectionSize into its own trait.
RenderUnit -> RenderSprites + WithFacingSpriteBody upgrade rule
Remove RenderSimple dependencies of ThrowsParticle
and WithHarvestAnimation.
