cc: Don't consider padding for analysis.
Currently we analyze exactly what we raster. However, there
are cases like edge tiles on a layer that are padded, so that
the shader samples non-garbage values when it's interpolating
the texture values.
However, for analysis we don't need this padding, we can analyze
just the integer canvas, which allows us to properly detect solid
layer-edge tiles.
