| source | ソーステクスチャ (コピー元のテクスチャ) |
| dest | Destination RenderTexture, GraphicsTexture, or null to blit directly to screen. |
| mat | コピーに使用するマテリアル。マテリアルのシェーダーはいくつかの後処理のエフェクトを行う必要があります。 |
| offsets | フィルタリングオフセットの変数の番号。オフセットはピクセル単位です。 |
| destDepthSlice | The texture array destination slice to blit to. |

This is mostly used for implementing some post-processing effects. For example,
Gaussian or iterative Cone blurring samples source texture at multiple different locations.
BlitMultiTap sets dest to be the active render target (changing RenderTexture.active and GraphicsTexture.active), sets source as
_MainTex property on the material, and draws a full-screen quad. Each vertex of the quad
has multiple texture coordinates set up, offset by offsets pixels.
BlitMultiTap has the same limitations as Graphics.Blit.
