+Extensions for the Impress and Draw applications.
+
+source/pdfimport/ - PDF import
+
+ Uses an external poppler process to parse and handle PDF
+ import as draw shapes.
+
+source/minimizer/ - Presentation Minimizer
+
+ Shrinks presentations by down-scaling images, and removing
+ extraneous eg. embedded OLE content.
+
+source/presenter/ - Impress / Presenter Console.
+
+ This couples to sd/ in rather strange ways. Its design is
+ heavily mangled by an attempt to use only UNO interfaces
+ which are highly inadequate. This leads to somewhat
+ ridiculous situations. Activating in response to
+ configuration keys (for example), and the 'XPresenterHelper'
+ interface inside sd/ used to create and manage windows.
+
+ The main screen uses a hardware-accelerated
+ canvas (e.g. cairo canvas), while the entire secondary screen
+ uses a VCL-canvas that is created in
+ sd::framework::FullScreenPane::CreateCanvas().
+
+ The secondary screen contains 3 "Panes" which each have
+ 2 XWindows for the border area & the actual content,
+ and each content Pane is backed by a sd::presenter::PresenterCanvas
+ that wraps the FullScreenPane's canvas and does clipping.
