Hossein ea5641baee Updated README.md files to represent current code / use Markdown format
Previously, all of the README files have been renamed to README.md
and now, the contents of these files were changed to use Markdown
format. Other than format inconsistency, some README.md files lacked
information about modules, or were out of date. By using LibreOffice
/ OpenOffice wiki and other documentation websites, these files were
updated. Now every README.md file has a title, and some description.
The top-level README.md file is changed to add links to the modules.
The result of processing the Markdown format README.md files can be
seen at: https://docs.libreoffice.org/

# 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 `Pane`s 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.
