Example a/testing/heart_fibres: Show heart fibres with streamlines.

The comfile run by this example is as follows:

# Set the default tessellation to use 4 segments in each element direction.
# This command does not exist on older versions of cmgui. It is safe to ignore errors.
gfx define tessellation default minimum_divisions "4" refinement_factors "1";

#Tests reading in the heart, producing simple geometry from it and fibre
#oriented glyphs and streamlines. Also show iso-surfaces of lambda=0.75.
