One copy doesn't support partial raster into a buffer provided by TileManager
(which is what this fn controls). Instead, it handles partial raster internally
in its staging buffers.

Could rename to "CanPartialRasterIntoProvidedBuffer"?

I'm not sure I know what the best answer is, but I think it's weird to have this
return false.

Renamed this function to hopefully be clearer.
