Example document with inserted SVG picture, SVG picture itself and screenshots of the document and crop settings in various versions of LO Writer.

Problem description: 

Steps to reproduce:
1. Open the "Front_page.odt" document found in attached zip archive.

Current behavior:

As of version 4.0.x of LO Writer, inserted SVG pictures are not croped properly if scaled. They are croped properly only if left in original scaling. Also, it seems only SVG pictures are affected, or maybe only vector images, because inserted PNG pictures do not exhibit this behavior.

In attached zip archive you will find screenshots of "Front_page.odt" file as it is displayed in LO Writer 3.6.7, 4.0.5 and 4.1.1 along with screenshots of settings in "Crop" dialog. The document is correctly displayed only in version 3.6.7 of LO Writer. Later versions display it incorrectly. Version 4.1.1 of LO Writer additionally displays the picture in color instead of light gray which is another bug I'll report separately.

It seems as if the order of operations - croping and scaling - is reversed in 4.0.x and later versions. Croping is done after upscaling so croping amount of, for example, 0.5cm is relative to upscaled size of the picture, for example 15x15cm. On the other hand, in version 3.6.7 croping amount is relative to original size of the picture (around 2x2cm) and upscaling is done after croping. The problem with versions 4.0.x and later is that they show the same croping preview (in "Crop" dialog) as version 3.6.7 but document is displayed differently than what is shown in the preview. Additionally, croping values in 4.0.x and later can not be larger than 2cm or so because that is the original size of the picture.

Expected behavior:

LO Writer versions 4.0.x and later should display the attached document the same way as version 3.6.7.
