Gathers user-specified Texture data into sourceRenderTexture.
This function collects Texture data from all Terrain tiles in the PaintContext, and merges that data into sourceRenderTexture.
The terrainSource function specifies what data to collect from each Terrain.
Gather assumes that the Texture data, which terrainSource returns, is mapped over the Terrain tile in a manner similar to the Heightmap and Alphamaps.
First, the function clears sourceRenderTexture to defaultColor.
Then, it uses the following steps to gather each Terrain in the PaintContext:
1) Calls terrainSource to retrieve the Texture.
2) Calls beforeBlit.
3) Uses blitMaterial and blitPass to copy The Texture into sourceRenderTexture.
4) Calls afterBlit.
