| source | Source texture. |
| dest | Destination RenderTexture, or null to blit directly to screen. |
| mat | Material to use for copying. Material's shader could do some post-processing effect, for example. |
| pass | If -1 (default), draws all passes in the material. Otherwise, draws given pass only. |
Copies source texture into destination render texture.
This is mostly used for implementing image effects, and requires Unity Pro.
Blit sets dest to be active render texture, sets source as
_MainTex property on the material, and draws a full-screen quad.
