virtual void SetScaleToPowerOfTwo(bool scale)
Should we produce images at powers of 2, makes rendering on old OpenGL hardware easier.
virtual vtkVector2i GetBounds(vtkTextProperty *property, const vtkUnicodeString &string, int dpi)=0
Given a text property and a string, get the bounding box [xmin, xmax] x [ymin, ymax].
