1) I'm not really able to match NEW with you're remarks.. Which part did you
exactly confirm?

2) Slightly out of scope of my initial report. 

Level 1 Initial size
The dimensions of an image will be calculated based on available pixels & DPI.
If DPI is embedded in the file embedded DPI will be used to calculate
dimensions. If not available the fallback will be screen DPI (didn't if there
was some change here, Tomaz was working on something).

'original size' means is to me dimensions embedded in file. A fallback size
because lack of DPI is 'some size'. You can technically say: it's the original
size at import time for LibreOffice. But to it's an arbitrary size from user
perspective with 'advanced level' of knowledge.

Level 2 Correction
If the image dimensions calculated at 'level 1' exceed page margins it will be
downsized to fit within margins regardless of the original dimensions (for
Writer; didn't check the rest)

If you press original size it will restore the 'level 1' dimensions. Which
isn't by definition the size at insertion time (as it shrinks to page margins)
which can be perceived as 'original size' from user perspective. 

Which is yet again one of ambiguity's of 'original size' And produces often a
non-functional result (image of 50x30 on A4 paper).
Original size works (only) perfectly for for image who fit within page margins
anyhow..

Another issue being that 'original size' being less useful
* where DPI isn't embedded in file (pretty common)
* A DPI being embedded, but far to low (have seen this couple of times)

I personally prefer a smaller image by dimensions (not file size) with high DPI
instead of hug image with low DPI

Point being: I still not totally grasp what 'original size' exactly attempting
to do. In my perception it only works out in say 50% of the cases. 

I also struggle with the label - aside from functionality part. It's more
default/initial dimensions. 

-------------------
Off topic

Being able to define image size on 'crop tab' (called scale) and "type tab"
also not great (but well that's Bug 132853)

And I would love some feedback of consequences of manual defined dimensions for
DPI (on the type tab). So increase of dimensions lowering the DPI. And decrease
of dimensions increasing DPI. When resizing an image mostly to take DPI account
(to prevent crappy quality). Another interesting option would be defining size
by DPI.

Dialog space isn't the issue. If it exceeds the limits of what a Word processor
should be able to do, well.. I would take usefulness as benchmark; I think it's
useful (but well I'm not the general public)
