Plotting a rectangle with the FLTK backend results in poor corners. The lines
do not meet such that the corner looks nice. On screen, this issue occurs with
all four corners. If the plot is saved to a file, the issue only occurs with
the lower right corner (see attachment).

Here's some code to illustrate the problem:

rectangle ( 'Position',[ 1 1 2 2] , 'Linewidth',10 )
axis ( [0 4 0 4] )
print ( 'test.png' )
