| source | @param source Текстура-источник. |
| dest | @param dest RenderTexture, или null для замены напрямую на экран. |
| mat | @param mat Материал, используемый при копировании. Шейдер материала делает какой-нибудь пост-эффект. |
| offsets | Variable number of filtering offsets. Offsets are given in pixels. |
| destDepthSlice | The texture array destination slice to blit to. |
Копирует текстуру-источник в конечную текстуру для многоэтапного шейдера.
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 active render texture, 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.
