> The default, implementation of {{GridCoverage.evaluator()}} returns an instance of the package-private {{DefaultEvaluator}} class. The {{apply(DirectPosition)}} method of that class requested a {{RenderedImage}} of size 1×1 pixel every times that the method is invoked. This is inefficient. We should request an image of the size of a tile, for example 512×512 pixels, and cache it.
> This work may require the completion of {{TileMatrix}} work, because we may try to align the requests to the size and position of existing tiles.
> Having larger sizes also allow the use of bilinear or other interpolations, which are currently not implemented in {{DefaultEvaluator}}.
