Sprites getting culled no rendered when using tile and slice mode

This is due to a known issue caused by the culling system calculating the viewable sprites based off the sprites original size/bounds from the origin, instead of the tiled size/bounds. Since the original bounds don't fall inside the camera view they get culled.

Possible solutions:

• In the Sprite Renderer component change the Draw Mode to Simple, and duplicate the sprite game objects manually to have them repeating in the game world.
• Repeat/Tile a texture on a quad, but make sure that it's power of 2.
