   * Powerpoint writer (Jesse Rosenthal):
 
     + Change reference to `notesSlide` to `endNotesSlide`.
-      This will prevent confusion when speakers notes are implemented.
-    + Move image sizing into `picProps`.  Rather than passing around
-      attributes, we can have image sizing in the picProps and then
-      pass it along to write to XML.
+    + Move image sizing into `picProps`.
     + Improve table placement.
-    + Make our own `_rels/.rels` file.  The toplevel .rels file could
-      have a thumbnail image if taken from the template. Rather than
-      removing it from the inherited file, it's easier to just make our own.
-    + Import reference-doc images properly.  There was a glob error that
-      was leading to images from the reference-doc pptx not being imported.
+    + Make our own `_rels/.rels` file.
+    + Import reference-doc images properly.
     + Move `Presentation.hs` out of `PandocMonad`.
-    + Ignore anchor links to nowhere.  We don't convert a `#target`
-      `ExternalTarget` to an `InternalTarget` if `target` is not in the
-      `AnchorMap`. We just remove the link. This prevents broken links.
-    + Refactor into separate modules.  This separates the conversion into
-      separate modules (T.P.W.Powerpoint.Presentation, which defineds the
-      Presentation datatype and goes Pandoc->Presentation)
-      and (T.P.W.Pandoc.Output, which goes Presentation->Archive).
+    + Refactor into separate modules.  T.P.W.Powerpoint.Presentation

-    + Avoid overlapping blocks in column output.  Just as a slide can't
-      have an image and text on the same slide because
-      of overlapping, we can't have both in a single column. We run
-      `splitBlocks` on the text in the column and discard the rest.
+    + Avoid overlapping blocks in column output.
     + Position images correctly in two-column layout.
-      You can have two images side-by-side, or text alongside an image. The
-      image will be fit correctly within the column.
-    + Make content shape retrieval environment-aware.  We put
-      `getContentShape` and `getContentShapeSize` inside the P monad,
-      so that we can (in the future) make use of knowledge of what slide
-      environment we're in to get the correct shape. This will allow us, for
-      example, to get individual columns for a two-column layout, and place
-      images in them appropriately.
+    + Make content shape retrieval environment-aware.
     + Improve image handling.  We now determine image and caption placement
       by getting the dimensions of the content box in a given layout.

       the side of the content, for example).
     + Read presentation size from reference file.  Our presentation size is

-      easier to set different output sizes by supplying different reference

+      now dependent on the reference/template file we use.
     + Handle (sub)headers above slidelevel correctly.  Above the slidelevel,
       subheaders will be printed in bold and given a bit of extra space
       before them. Note that at the moment, no distinction is made between
       levels of headers above the slide header, though that can be changed.
-      (It has to be changed in pandoc, since PowerPoint has no concept of
-      paragraph or character classes.)
     + Check for required files.  Since we now import from reference/dist
       file by glob, we need to make sure that we're getting the files we
       need to make a non-corrupt Powerpoint. This performs that check.
     + Improve templating using `--reference-doc`.  Templating should work
       much more reliably now.
     + Include Notes slide in TOC.
-    + Set notes slide header with slide-level.  It used to be hardcoded to 2.
-      This will set it to the appropriate slide-level.
+    + Set notes slide header to slide-level.
     + Add table of contents.  This is triggered by the `--toc` flag. Note
       that in a long slide deck this risks overrunning the text box. The user
       can address this by setting `--toc-depth=1`.
-    + Set notes slide number correctly.  Previously, this hadn't been aware
-      of a metadata slide.
-    + Ignore internal links without targets.  If the user entered an
-      internal link without a corresponding anchor, it would produce a
