Reviewed by Fujii Hironori.

The needsUpdate state for flattened layers was incorrectly reset before the
layer was fully updated. This issue occurred when processing large layers
that required tiling, as the state was based on the number of tile textures
being greater than zero. This fix adjusts the logic to correctly account for
layers that require multiple tiles to render.
