Hi all,
During the development of new features in vtkMatplotlibMathTextUtilities (support for multilines and multicolumns in text representation), we noticed that the LineSpacing property of vtkTextProperty was defaulted to 1.1, and not 1.0 as it should be. We included a commit to change the default to 1.0.
We updated the impacted baseline, but please notice that this will change the aspect of the rendering of every multiline text. Just set vtkTextProperty::LineSpacing to 1.1 to have old defaulted behavior.
