Fix TextureView texture filtering.

bug:11748993

TextureView should always be drawn with linear filtering if drawing a
buffer sized differently from the layer.

This fixes a bug where TextureViews that were sized differently from
their contents wouldn't be drawn with texture filtering, causing
visible scaling artifacts.
