automatically adjust point/line sizes for screenshots with different resolution
If you have points or lines in the scene and you take a screen shot at a higher resolution than the current window (say 5000x5000), many of the objects stay the same size (spheres, planes, triangulated meshes) but many objects get much smaller (points, lines). Surely this is because the points and lines are specified in arbitrary units (Point Size = 3, Line Width=2, for example). An example is here:
Notice the lines in the screenshot are much thinner.
It would be nice to have theses sizes automatically adjusted to the relative difference between the screenshot size and the render window size, so screenshots will look the same.
