 * Applies a transform matrix to a {@link Primitive}.
 *
 * All vertex attributes on the Primitive and its
 * {@link PrimitiveTarget PrimitiveTargets} are modified in place. If vertex
 * streams are shared with other Primitives, and overwriting the shared vertex
 * attributes is not desired, use {@link compactPrimitive} to pre-process
 * the Primitive or call {@link transformMesh} instead.
 *
 * Example:
 *
 * ```javascript
 * import { fromTranslation } from 'gl-matrix/mat4';
 * import { transformPrimitive } from '@gltf-transform/functions';
 *
 * // offset vertices, y += 10.
 * transformPrimitive(prim, fromTranslation([], [0, 10, 0]));
 * ```
 *
 * @param prim
 * @param matrix
