Helper function for completing a texture alphamap modification.
Once the modified data is written to PaintContext.destinationRenderTexture, call this function to copy the modifications back to the original Terrains.
This function also signals Unity to recalculate the basemap.
This function will also release all allocated resources in the PaintContext.
