A Texture capable of storing many smaller Textures with offsets. A Texture capable of storing many smaller Textures with offsets. You can dynamically add pieces([Texture]) to this [LargeTexture] using different offsets. Add another [Texture] to this [LargeTexture], starting on offset "ofs". Clears the [LargeTexture]. Returns the number of pieces currently in this [LargeTexture]. Returns the offset of the piece with index "idx". Returns the [Texture] of the piece with index "idx". Sets the offset of the piece with index "idx" to "ofs". Sets the [Texture] of the piece with index "idx" to "texture". Sets the size of this [LargeTexture].
