This patch adds a GetBoundingBox function to vtkMathTextUtilities and applies rotations from the supplied vtkTextProperty. The matplotlib MathText interface doesn't have an entry point to just get the bounding box, so the image is rendered by python as normal, and then the dimensions are returned. The MathText library doesn't support rendering rotated text directly, so a vtkImageReslice filter is used to rotate the image. Change-Id: I65be970af47c7f8de65f6279c922b6b001f62780
