AnimClipSizing
AnimClipSizing =
"entity"|"frame"
Defined in: animation/AnimClipLoader.ts:46
Who owns Sprite.size while the clip plays. 'entity' — the default, and what
every clip written before format 1.5 does — leaves the entity’s size alone, so
every frame draws at that one size. 'frame' hands size to the clip and each
frame draws at its own, which is what lets frames of DIFFERENT sizes share a clip.
