   // attribute). So if our input surface or filter is smaller than the source
   // rect, we need to add transparency around it until we reach the edges of
   // the source rect, and only then do any repeating or edge duplicating.
   // Unfortunately, D2D1 does not have any "extend with transparency" effect.
   // (The crop effect can only cut off parts, it can't make the output rect
   // bigger.) And the border effect does not have a source rect attribute -
   // it only looks at the output rect of its input filter or surface.
   // So we use the following trick to extend the input size to the source rect:
   // Instead of feeding the input directly into the border effect, we first
   // composite it with a transparent flood effect (which is infinite-sized) and
   // use a crop effect on the result in order to get the right size. Then we
   // feed the cropped composition into the border effect, which then finally
   // feeds into the convolve matrix effect.
   // All of this is only necessary when our edge mode is not EDGE_MODE_NONE, so
   // we update the filter chain dynamically in UpdateChain().

   // premultiplied and unpremultiplied inputs, and they always premultiply
   // their result - at least in those color channels that have not been
   // disabled.
   // In order to determine whether the input needs to be unpremultiplied as
   // part of the transfer, the effect consults the alpha mode metadata of the
   // input surface or the input effect. We don't have such a concept in Moz2D,
   // and giving Moz2D users different results based on something that cannot be
   // influenced through Moz2D APIs seems like a bad idea.
   // We solve this by applying a premultiply effect to the input before feeding
   // it into the transfer effect. The premultiply effect always premultiplies
   // regardless of any alpha mode metadata on inputs, and it always marks its
   // output as premultiplied so that the transfer effect will unpremultiply
   // consistently. Feeding always-premultiplied input into the transfer effect
   // also avoids another problem that would appear when individual color
   // channels disable the transfer: In that case, the disabled channels would
   // pass through unchanged in their unpremultiplied form and the other
   // channels would be premultiplied, giving a mixed result.
   // But since we now ensure that the input is premultiplied, disabled channels
   // will pass premultiplied values through to the result, which is consistent
   // with the enabled channels.
   // We also add an unpremultiply effect that postprocesses the result of the
   // transfer effect because getting unpremultiplied results from the transfer
   // filters is part of the FilterNode API.
