Error at displaying the object with changed scale at its (object's) movement

[tiket18]

The error is declared in any branch of the program version 0.19.

We create a sketch.
Create link to sketch.
Change the scale of the link = see on the screen a sketch with a named scale -

We are trying to change thumbnail position settings - the first time you change the position settings, the view of this thumbnail on the screen becomes 100% (no changes are made in the zoom settings) -

scale.FCStd.zip

We would also like to ask for a new feature. The program is good at importing svg and you can convert it into sketches. But all such thumbnails are in splines. This is very expensive from a computational point of view, especially when used later to extrude a volume body. There is no tangent or adjunction to a spline. It is very, very, very difficult to transform inside a sketch of a spline into simple geometries - so that there are 2 degrees of freedom (moving X and Y of the entire connected geometry).
