The Bluetooth communication appears to be astonishingly slow on my system; the socket is deliberately cleared of O_NONBLOCK and what's even worse is that the Mutex that is held while sending prevents the main thread from adding new messages to the queues. It looks like there should be no issue with releasing the Mutex while sending, and if a separate Transmitter thread is used in the first place it makes no sense to hold the Mutex while doing so.

LibreOffice Impress / Draw Application
The core directory for the impress/draw applications.
Think of impress as a hack on top of draw.
sd module contains impress/draw specific code, non-shared UI and part
of ppt and pptx filter, few other filters too.
the slideshow UI lives here as well, the slideshow engine is in
slideshow module though (including the 3D transitions engine
slideshow/source/engine/opengl).
the most used filters are ODF's odp, binary ppt and OOXML's
pptx. their locations are listed below:
-
odpimport and export filters are inxmloffmodule (mostlyxmloff/source/draw) -
pptimport is insd/source/filter/ppt(big shared chunks are also insvx) -
pptexport is insd/source/filter/eppt(big shared chunks are also insvx) -
pptximport is inoox/source/ppt(and uses a lot ofoox/source/drawingmlandoox/source/*) -
pptxexport is insd/source/filter/eppt(mostly inpptx-*source files) and shared part is inoox/source/export
PPTX Export / Import Filters
PPTX export filter is split into 2 parts. Impress related part is in
sd/source/filter/eppt/pptx-* and the other part is in
oox/source/export/ because it contains mostly code related to
DrawingML, which is shared with writer and calc ooxml export.
The export filter was written in 2009 IIRC and was not much extended feature-wise lately.
Future Works
Add custom shapes export (see below). enhance text
output, we don't write text style for indentation levels now, need to
export a:lvl1pPr, a:lvl2pPr, ... elements.
PPTX import was written by Sun/Oracle and then extended in LibreOffice
a lot during bug fixing. It is located in oox/source/ppt and
oox/source/drawingml. The areas with most bugs (at least until today)
were shape placeholders and text style inheritance.
