Description Callegar 2018-01-31 11:14:38 UTC 
Description:
When using autofit text boxes in impress, text is automatically scaled to fit the box.

If some paragraphs have margins set to some width tighter than the box width, they are respected as long as text is not scaled. When text is scaled the margins are wrong.

Steps to Reproduce:
1. Open impress
2. Insert some text in a slide, using the default box that, by default, should have autofit on (if it does not have autofit on, switch it on). Assure that the text has multiple paragraphs. Also, assure that enough text is put in the box that the autofit function can operate, by rescaling the text.
3. Put the text cursor in one paragraph. Now, go the the margins ruler and drag the right margin pointer left. While you do so, a thin vertical line should appear across the slide, indicating the actual place where the text should wrap because of the margin. Choose some point about halfway through the slide text box.


Actual Results:  
Observe that the paragraph is actually been reflowed to a tighter right margin, but not as much as it should. Text does not end at the place where the vertical line appeared during the margin set, but to the right of it. The actual error depends on the scaling that was applied because of autofit. The larger the rescaling, the larger the error. 

Expected Results:
The paragraph should be reflown ending at the place where the vertical line appeared during the margin set.


Reproducible: Always


User Profile Reset: No



Additional Info:
I think that LibO forgets to "internally adjust" the after text indent according to the scaling.

It seems that the right margin is scaled with the same factor as the font size. Font size 32pt, margin right 5cm is scaled down to font size 24pt, margin about 3.8cm for example.
I think, that it is error, because this attribute should only change the displayed font size.
I have tested it in Version: 6.1.0.0.alpha0+ (x64)
