2018-01-17	Powerpoint writer: Use slideids to simplify code.	Jesse Rosenthal	1	-23/+25

2018-01-17	Powerpoint writer: Revamp slide type	Jesse Rosenthal	1	-33/+82
	This is an internal change to the Presentation type. The algebraic datatype that used to be called `Slide` is now `Layout`, and Slide is defined as `Slide SlideId Layout (Maybe Notes)`. Though there should be no user-visible changes in this commit, it offers two benefits moving forward: 1. Slides now carry their Id with them, instead of being assigned it in deck order. This makes it easier to set up a link to, say, an endnotes slide ahead of time. 2. This makes room for Notes slides, when we implement them.
2018-01-17	Powerpoint writer: Change reference to notesSlide to endNotesSlide	Jesse Rosenthal	1	-11/+11
	This will prevent confusion when speakers notes are implemented.
2018-01-17	Powerpoint writer: Move image sizing into picProps.	Jesse Rosenthal	1	-8/+24
	Rather than passing around attributes, we can have image sizing in the picProps and then pass it along to write to XML.
2018-01-15	Powerpoint writer: Move Presentation.hs out of PandocMonad	Jesse Rosenthal	1	-33/+36
	We don't need it for anything but the log messages, and we can just keep track of that in state and pass it along to the `writePowerpoint` function. This will simplify the code.
2018-01-15	Powerpoint writer: Ignore anchor links to nowehere.	Jesse Rosenthal	1	-3/+6
	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 in the Powerpoint output.
2018-01-14	Powerpoint writer: Fix anchor links.	Jesse Rosenthal	1	-17/+59
	They were broken when I refactored (the Output module wanted to use state left over from the construction of the Presentation type). This change introduces a new type `LinkTarget = InternalTarget \| ExternalTarget`. Internal target points to a slide number, and these will all be resolved before the Presentation is passed along to the Output module.
2018-01-14	Powerpoint writer: Refactor into separate modules.	Jesse Rosenthal	1	-0/+701
	There are two steps in the conversion: a conversion from pandoc to a Presentation datatype modeling pptx, and a conversion from Presentation to a pptx archive. The two steps were sharing the same state and environment, and the code was getting a bit spaghetti-ish. 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). Text.Pandoc.Writers.Powerpoint a thin wrapper around the two modules.
