Multisampling prop isn't passed corerctly to EffectComposer

[whereiswolf]

Describe the bug

The multisampling prop on <EffectComposer /> is incorrectly passed to postprocessing's EffectComposer constructor.

Reproduction A Stackblitz example: https://stackblitz.com/edit/tresjs-multisampling-bug?file=src%2Fcomponents%2FNoAliasing.vue

Steps Steps to reproduce the behavior:

1. In a scene add <EffectComposer :multisampling="8" /> and any other effect you want (tested on Outline / Vignette)
2. The aliasing occurs.

Expected behavior The EffectComposer passess multisampling prop correctly to postprocessing's EffectComposer, and enables mutlisampling.

Screenshots If applicable, add screenshots to help explain your problem.

👇 With <EffectComposer :multisampling="8" />

☝️ Without post-processing and with default antialiasing.

Additional context The problem's with a reverse order of multisampling checks in effectComposerParams:

// src/core/EffectComposer.vue
...
const effectComposerParams = computed(() => {
  const plainEffectComposer = new EffectComposerImpl()
  const params = {
    depthBuffer: props.depthBuffer !== undefined ? props.depthBuffer : plainEffectComposer.inputBuffer.depthBuffer,
    stencilBuffer:
      props.stencilBuffer !== undefined ? props.stencilBuffer : plainEffectComposer.inputBuffer.stencilBuffer,
    multisampling: isWebGL2Available()
-      ? 0
-      : props.multisampling !== undefined
-        ? props.multisampling
-        : plainEffectComposer.multisampling,
+      ? props.multisampling !== undefined
+        ? props.multisampling
+        : plainEffectComposer.multisampling
+      : 0,
    frameBufferType: props.frameBufferType !== undefined ? props.frameBufferType : HalfFloatType,
  }
  plainEffectComposer.dispose()

  return params
})
